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.

Each photograph is captioned with what it shows. There are no case-study numbers on this page 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.

Vaillant aroTHERM plus 7 kW air source heat pump installed in Islington N1

Heat pump

Islington N1

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.

Heat pump, solar and battery

Finsbury Park N4

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.

Greater London
Vaillant aroTHERM plus air source heat pump installed in Hornsey N8

Heat pump

Hornsey N8

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.

Air source heat pump with roof-mounted solar installed in Winchmore Hill N21

Heat pump and solar

Winchmore Hill N21

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.

Mitsubishi Ecodan air source heat pump installed in Winchmore Hill N21

Heat pump

Winchmore Hill N21

Mitsubishi Ecodan air source heat pump

An Ecodan stood off the boundary fence far enough that the fan discharge is not bouncing straight back off it, which is what makes a badly sited unit sound louder than it is.

Cascade pair of air source heat pumps installed in Barnet EN4

Heat pump

Barnet EN4

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.

Daikin multi-split condenser installed in New Southgate N11

Air conditioning

New Southgate N11

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.

Air conditioning in New Southgate N11
Samsung monobloc air source heat pump installed in Wood Green N22

Heat pump

Wood Green N22

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.

Air source heat pump with solar and battery storage installed in Tottenham N15

Heat pump, solar and battery

Tottenham N15

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.

Air conditioning in Tottenham N15
Samsung monobloc air source heat pump installed in Camden NW1

Heat pump

Camden NW1

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.

Samsung monobloc air source heat pump installed in Leytonstone E11

Heat pump

Leytonstone E11

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.

Samsung air source heat pump installed in Walton-on-Thames KT12

Heat pump

Walton-on-Thames KT12

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.

Air conditioning in Walton-on-Thames KT12
Samsung air source heat pump installed in Epsom KT19

Heat pump

Epsom KT19

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.

Vaillant twin-fan air source heat pump installed in Wimbledon SW19

Heat pump

Wimbledon SW19

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.

Samsung heat pump with Tesla Powerwall installed in Hemel Hempstead HP1

Heat pump and battery

Hemel Hempstead HP1

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.

What you are looking at

The things in these photographs that decide whether a system is quiet, efficient and still working in ten years.

The base

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.

The clearance

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.

The pipework

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.

Questions about this work

Are these your own installations?

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.

Why are there no prices next to the jobs?

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.

Most of these are heat pumps. Do you fit air conditioning too?

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.

Will you show me a job near me before I commit?

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.

Book the survey that produces the fixed price

We come out, measure the property, and give you a written price that does not change. No cost, no obligation, and no salesperson.

Monday to Friday 9am to 7pm, Saturday 10am to 3pm, Sunday closed
