These are installations carried out by Electro Heating Limited, which trades as Climate Shield London. The same engineers who survey a job carry it out, and the certification is issued in the company's name.
Every project below opens its own case study: the equipment, where each part went and why, and the photographs from the job. There are no savings claims, because savings depend on the house, the tariff and how the system is run, and a figure from someone else's home tells you nothing reliable about yours.

Air conditioning
Daikin multi-split, four rooms from one outdoor unit
One outdoor unit on the rear patio serving four indoor units, with the pipework taken up the back wall in trunking beside the downpipe and pressure tested with nitrogen at 40 bar for two hours before it was charged.

Air conditioning
LG wall-mounted air conditioning, fitted during a renovation
A large open-plan room in a house being renovated: the lines brought down from the ceiling first, the brackets fixed over them, and the LG units lifted on high on the wall.

Air conditioning
Daikin multi-split condenser
Wall-mounted on brackets rather than stood on the ground, which is usually what a narrow side return leaves you, and the refrigerant lines dropped in a single trunked run.
Read the case study
Air conditioning
Air conditioning pipework in a new nursery, first fix
A nursery still being built: the refrigerant pipework and control cables run through the ceiling void above the corridor and down a riser between floors, tied in and sealed, before the ceilings and walls are closed.

Heat pump
Vaillant air source heat pump
In the side passage on feet, levelled before it was connected, with a buffer tank, hot water cylinder and underfloor heating manifold together in one cupboard inside.

Heat pump and solar
Air source heat pump with roof-mounted solar
The panels sit across the rear pitch and the heat pump at the side of the house, which is the pairing that lets the pump run on its own generation through the middle of the day.

Heat pump
Samsung monobloc air source heat pump
Stood on a levelled base built up out of the border rather than on soil, so the feet stay out of standing water and the unit does not settle out of level over a winter.
Read the case study
Heat pump
Samsung monobloc air source heat pump
Set tight against the flank wall on anti-vibration feet, where it takes up none of the usable garden and the pipe run to the cylinder stays short.
Read the case study
Heat pump
Vaillant aroTHERM plus 7 kW air source heat pump
Stood on rubber anti-vibration blocks on the existing patio slabs rather than on a new base, against the rear fence and beside the drainage the house already had.
Read the case study
Heat pump, solar and battery
Air source heat pump with solar and battery storage
The whole electrical side on one wall: inverter, battery modules and every isolator in reach, with the conduit dressed in straight runs so a fault years from now can be traced without stripping the wall.
Read the case study
Solar
Solar panels on a brick wall and on the roof
Some panels flat against a brick wall on black rails, the rest in a row along the roof slope with bird spikes along the lower edge and every frame bonded to earth.
Read the case study
Solar and battery
Solar panels on ballasted frames, flat roof
Low-tilt frames standing on the pebble finish of a new-build flat roof and held down by weight, so nothing is fixed through the waterproofing, with a clear strip left along the parapet to walk and work from.
Read the case study
Heat pump
Samsung monobloc air source heat pump
Levelled on packers on an existing tiled patio rather than bolted through it, so the tiling stays intact and the unit still sits dead flat.
Read the case study
Heat pump
Samsung Gen 7 12kW high temperature heat pump
On wall brackets on the side of the house, clear of the ground, which keeps the side passage usable and the coil away from leaves and splashback.
Read the case study
Heat pump
Cascade pair of air source heat pumps
Two machines in cascade on a flat roof, flow and return in insulated copper with isolating valves on each leg, so one can be shut down and worked on while the other keeps the building warm.
Read the case study
Heat pump
Samsung monobloc air source heat pump
On its own slab set clear of the fence line, with the condensate taken away below ground level instead of being left to run across the paving and freeze.
Read the case study
Solar
Roof-mounted solar array
Two panels on the slate roof of a single-storey extension, each with its own microinverter, and bird mesh clipped round the edge so nothing can nest underneath.
Read the case study
Solar
Solar panels on ballasted trays, flat roof
Six panels on the flat dormer roof, tilted on weighted trays rather than bolted down, so the roof covering is not pierced anywhere and the array still faces the sun instead of lying flat.
Read the case study
Heat pump
Air source heat pump
Flow and return brought up the wall as one insulated pair in a single clipped run, which is the difference between pipework that looks designed and pipework that looks added.
Read the case study
Heat pump
Vaillant twin-fan air source heat pump
A larger twin-fan machine raised onto a brick plinth, which lifts the coil clear of leaf litter and puts the fans above the level a low fence would reflect.
Read the case study
Heat pump
Bosch air source heat pump
Installed on a flat roof on a raised frame, so the roof covering carries no point load and rainwater still runs freely underneath.
Read the case study
Heat pump
Samsung air source heat pump
Fitted down the side passage on a proper base, with the isolator mounted at the house wall where it can be reached without walking past the unit.
Read the case study
Heat pump
Samsung air source heat pump
Set into a planted border on a hard base, far enough off the wall for the service access the manufacturer asks for and close enough that the pipe run stays short.
Read the case study
Heat pump
Samsung air source heat pump
Sited round the corner from the conservatory glazing rather than beside it, because a fan discharging at glass is the most common cause of a noise complaint about a unit that is running perfectly.
Read the case study
Heat pump and battery
Samsung heat pump with Tesla Powerwall
Heat pump and battery on the same elevation, so the pump can be run off stored generation through the evening peak instead of off the most expensive electricity of the day.
Read the case study
Heat pump
Vaillant aroTHERM plus air source heat pump
An aroTHERM plus on a poured pad against the boundary fence, with the drain point brought out through the pad so the defrost water has somewhere to go.
Read the case study
Heat pump
Vaillant aroTHERM plus air source heat pump
A gas boiler out and a heat pump in over three days, a few streets from our own base. The unit stands beside the garden decking on anti-vibration feet, with the pipework taken along the fence line.
Read the case study
Heat pump
Vaillant aroTHERM plus 7 kW air source heat pump
Replaced an old gas boiler in three days. Raised on feet over a gravel bed at the side of the garden, so the defrost water drains away rather than pooling round the base.
Read the case study
Heat pump
Vaillant aroTHERM plus 7 kW air source heat pump
There was no room for it in the garden, so it went on the flat roof, stood on rubber blocks over a protective mat so the roof covering carries no point load.
Read the case study
Heat pump, solar and battery
Vaillant air source heat pump with solar panels and a battery
The panels on the roof run the heat pump through the day and the battery carries it into the evening, so the house buys far less from the grid. The unit sits on raised feet against the rear wall.
Read the case study
Heat pump
Vaillant aroTHERM plus air source heat pump
The owner wanted the indoor equipment out of the living space, so it went into the loft. The outdoor unit has its own base in the garden. Three days, gas boiler out.
Read the case study
Heat pump
Vaillant aroTHERM plus air source heat pump
Fitted in three days as part of a renovation, replacing the gas boiler. It now runs the underfloor heating and the hot water, from a unit on blocks in the side return.
Read the case study
Heat pump
Vaillant aroTHERM plus 7 kW air source heat pump
Built around underfloor heating during a renovation: the old system out and the heat pump running in three days, set on anti-vibration feet on a level base against the fence.
Read the case study
Heat pump
Vaillant aroTHERM plus air source heat pump
A smaller unit, sized to what the house actually needs rather than rounded up, fitted in three days during a renovation. It stands on blocks against the house wall.
Read the case study
Heat pump
Vaillant aroTHERM plus air source heat pump
Gas boiler to heat pump in three days, with the grant approved within 48 hours. The unit stands on anti-vibration feet on a concrete pad close to the house, which keeps the pipe run short.

Heat pump
Vaillant aroTHERM plus air source heat pump
Set into the corner of the garden against the fence on a raised base, clear of the lawn, replacing a gas boiler over three days.
Read the case study
Heat pump
Vaillant aroTHERM plus 7 kW air source heat pump
A Holland Park house taken off gas in three days. The outdoor unit fits a narrow side passage, and the cylinder is only a short run away from it.
Read the case study
Heat pump
Samsung 12 kW high temperature air source heat pump
A two-zone system with a 300-litre cylinder and a buffer tank, 15 metres of pipework run underground to the unit on its own concrete base, and radiators replaced where they were too small for a heat pump.
Read the case study
Heat pump
Vaillant aroTHERM plus 7 kW with a 300-litre cylinder
Outside, the unit stands against the side wall on its feet. Inside, a 300-litre uniSTOR cylinder, wireless controls and a 25-litre buffer vessel.
Read the case studyThe things in these photographs that decide whether a system is quiet, efficient and still working in ten years.
Every unit here stands on something built for it: a poured pad, a plinth, a raised frame on a flat roof. A heat pump left on soil settles out of level, and a compressor out of level is a compressor wearing out early.
Manufacturers publish a minimum distance to the wall behind and in front of the coil. Ignore it and the unit re-breathes its own cold discharge air, the efficiency drops in exactly the weather you bought it for, and it ices up more often.
Flow and return insulated as one clipped pair, condensate taken somewhere it can actually drain, isolating valves where an engineer can reach them without dismantling anything.
Yes. They were carried out by Electro Heating Limited, company number 12609754, which is the company trading as Climate Shield London. It is the same legal entity, the same engineers and the same certification, under the name we use for this work.
That is why the photographs can be published with the equipment and the location on them. They are not a portfolio bought in or borrowed.
Because the quotations belong to the customers who received them. What we can publish is the shape of the pricing across many jobs, and that is what the cost pages and the calculators are built from.
If you want a number for your own property, the survey is free and the written price after it does not move.
Air conditioning is the larger part of what we do; it is simply photographed less, because an indoor unit on a wall makes a duller picture than a machine in a garden. There is a Daikin condenser from New Southgate on this page and more on the installation page.
An air-to-air heat pump and an air conditioner are the same machine. If you want heating and cooling from one system, that is the one to ask about.
Where a customer has agreed to it, yes. Ask at the survey and we will tell you what we have nearby and whether that householder is happy to be contacted.
We will not give out an address or a name without that permission, which is the same protection you get.
We come out, measure the property, and give you a written price that does not change. No cost, no obligation, and no salesperson.
