Air-to-water heat pumps

Flow temperatures are lower than with a typical boiler, which is why radiator sizing is part of the survey.

Hot water cylinders

Cylinder size is based on your household’s needs.

Air source heat pumps in Whetstone, done properly

Air source heat pumps collect heat from outdoor air and bring it inside, using electricity to drive the process. It works on the same principle as air conditioning, run the other way and the Energy Saving Trust notes that air-to-air heat pumps are sometimes referred to as air conditioning. The work covers air-to-air heat pumps, underfloor heating and hot water cylinders, and the jobs we see most are checking whether planning permission is needed and working out where a cylinder could go.

A terrace in Whetstone shares walls with its neighbours, which helps keep heat in, provided the outdoor unit can sit somewhere that passes the MCS noise check.

Warranty periods vary by brand and by product. For example, Daikin’s standard warranty on split air conditioning is 2 years, and its longer extensions apply to its air-to-water units only. For any other brand, we explain the manufacturer’s terms on your quote.

What we do, step by step

Think of the visit in three stages: diagnose, treat and sign off. First comes a careful look at the system or the space, then we do the work, and finally we test, record and explain. Most of the time goes on the middle part, which takes several days for an air-to-water system with a new cylinder, less for an air-to-air system. For a job in Whetstone, tell us about parking, permits and access to the building when you get in touch.

  1. It starts with a conversation about the home, the existing heating and your plans.
  2. A heat loss survey works out how much heat each room needs, and we look at the radiators, the cylinder space and where the outdoor unit could go.
  3. We send a fixed-price quote that shows the equipment, the grant position and the VAT.
  4. The outdoor unit, the indoor equipment and the controls are installed and connected.
  5. Once it’s running correctly, the MCS certificate is issued and we show you the settings.

Before we arrive

  • Clear the space around the indoor unit, or where it will go
  • Find the manual or the paperwork for the system, if you have it
  • Unlock any gate, garage or side passage we need

Heat pumps in Whetstone: local notes

VOA council tax data show about 32% of homes in and around Whetstone date from 1919 to 1939, and Census 2021 figures found about 50% of households live in flats. Whether the walls and loft have been insulated makes a real difference to the heat pump size for homes of that period. For flats, the first questions are where an outdoor unit could go, whether a cylinder fits and what the lease allows. For a London home, the outdoor unit position and the MCS noise check need careful planning.

Historic houses such as Heath Hall, about 3.5 miles south, are a reminder that listed homes need consent before a heat pump goes in.

Questions from Whetstone

Can you fit air conditioning in a London flat in Whetstone?

In many cases, yes, once the lease and the building’s rules are checked. Permitted development rules for flats are tighter than for houses, so we check the outdoor unit position and give you the details to send to the freeholder or managing agent.

Is planning permission needed for a heat pump in Whetstone?

That depends on the building and where the outdoor unit goes. Around 13 listed entries sit within 0.5 miles of central Whetstone. On a house, an air source heat pump can often go ahead under permitted development, with an outdoor unit of no more than 1.5 cubic metres and an installation that meets MCS 020(a), which includes a noise check. Those rights do not reach the grounds of a listed building, and conservation areas rule out walls or roofs facing a road. If that might affect you, we ask Barnet council, which is typically the planning authority for Whetstone.

Will you make a mess?

We put dust sheets over floors and furniture near the work first, and we tidy up as we go. Before we leave, we clear up and run through the work with you.

Is there a survey before the work?

Yes, always. Diagnosis comes before treatment: the survey tells us what the job needs and how to do it and the fixed price is built on it.

How soon will you get back to me?

The same working day. Then we agree a date that works for you, and you get a fixed price before any work goes ahead.

Which manufacturers do you install and repair?

We install and work on the leading makes, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Send us the make and model if you have it.

Do you offer maintenance contracts?

Yes. Maintenance contracts are part of what we do, with visits at the interval your system and the manufacturer need. Each visit is written up and F-Gas records kept where they apply.

Owner checks or an engineer?

Write down what you notice: error codes, noises, drips, smells or a drop in performance. It makes our diagnosis quicker, and a photo of the display helps even more.

Owner care supports servicing; it doesn’t replace it. Clean filters and a clear outdoor unit help the system run as it should, but the inside of the units, the refrigerant and the electrics still need a qualified engineer.

When to call us in Whetstone

Many enquiries start with a question about the Boiler Upgrade Scheme. Whether you can get the grant depends on your home and the scheme conditions and we confirm it before you go ahead.

These are the situations we see most often:

  • Choosing between air-to-water and air-to-air
  • Questions about listed buildings or conservation areas
  • Working out where a cylinder could go

Period properties close to Church of St John can suit a heat pump, though insulation and any heritage protection are checked first.

Before booking anyone

  • What paperwork you’ll receive afterwards
  • Whether the price is fixed or an estimate
  • Whether the electrical work is done by a registered contractor, such as NICEIC approved
