Air source heat pumps near Old Malden

About our air source heat pumps in Old Malden

We begin with a room-by-room heat loss survey. It shows how much heat each room needs on a cold day so the system is sized to match. Guesswork leads to systems that are too big or too small. If you are dealing with radiators that may be too small for a heat pump and comparing heat pump types, we can sort it out.

Homes around Old Malden normally have space for an outdoor unit and a hot water cylinder, so heat loss, radiators and the electrics are what we check.

Think of the paperwork as the system’s health record: what was fitted or found, what was done and when. It makes the next visit quicker and any warranty question simpler, so keep it safe.

What happens on the day

On the day, we arrive at the time agreed with you and check the plan with you first. Floors and furniture near the work are covered with dust sheets, and the electrics are made safe before any panel comes off. On site, it takes a few days on site, depending on the cylinder, the radiators and the pipework involved. In a place like Old Malden, parking is rarely an issue, but tell us about gates and access to the back of the property.

  1. We start with your plans and the property.
  2. We survey for heat loss and look at radiators, cylinder space and outdoor unit options.
  3. We explain which type of heat pump suits the home and whether a grant could apply.
  4. Installation follows on the agreed dates.
  5. We commission it, complete the MCS certificate and show you how to use it.

Before we arrive

  • Give us access to the outside wall, roof or yard where the outdoor unit sits
  • Tell us about access, such as roof hatches, high walls or locked plant areas
  • Clear access to the fuse board

Whether the walls and loft have been insulated makes a real difference to the heat pump size for homes of that period.

Fitznells Manor lies about 1.8 miles south-east. Owners of listed homes need consent before a heat pump is fitted, so it’s one of our first questions.

Common questions in Old Malden

Do you cover smaller places like Old Malden?

Yes. Old Malden is within the area we cover across London and the South East. Send a few details and photos, and we reply the same working day.

Can you do air source heat pumps in Old Malden?

Yes. Old Malden is one of the places we cover. Get in touch with the details and we reply the same working day.

Will I get records for the system?

Yes, always. A new system comes with commissioning details, F-Gas records and the manufacturer’s warranty information, while repairs and services get a written note of what was found and done.

Will you work on another installer’s system?

Yes. We work on systems fitted by other installers as well as our own from all the leading brands. Send us the make and model, and any records you have.

Why use an F-Gas certified company?

Certification shows a business is approved to work on systems that hold F gas refrigerant. In Great Britain, that certification is a legal requirement, not an optional extra, and we hold it.

Which brands do you work with?

The main ones, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. For a new system, we suggest the make and model that suit the property and tell you why.

Can I do any of the installation myself?

Anything that involves the refrigerant needs an F-Gas qualified engineer from a certified company. That is the law, not just our preference, and it also matters for the manufacturer’s warranty. We’re happy to quote for the full job, supply to commissioning.

Different systems, different jobs

Radiators and underfloor heating

Heat pumps run at lower flow temperatures, so radiators may need to be larger, and the survey checks each one.

Hot water cylinders

The cylinder size depends on how much hot water the household uses.

Landlords, agents and facilities managers

Running several properties is easier with one contractor. Our area covers Greater London and the South East, so a run of properties can go into one programme and kept on a regular cycle.

Whether it’s one property or many, you get the same standard: a look at the job first, a fixed-price quote, work booked with the occupier and written records afterwards.
