Air source heat pumps across Harlow

Air source heat pumps in Harlow

Heat pumps run at lower flow temperatures than most boilers, so radiators may need to be larger to give out the same heat. We check each radiator against the room’s heat loss, and the quote sets it out. The work covers radiator systems, air-to-water heat pumps and underfloor heating, and people most often call us about questions about listed buildings or conservation areas and radiators that may be too small for a heat pump.

Most homes around Harlow have space for the outdoor unit, and it needs to meet the MCS noise check to be permitted development.

Warranty periods vary by brand and by product. Daikin, for example, gives a standard 2 years on split air conditioning, with longer extensions only on its air-to-water heat pumps. For any other brand, we explain the manufacturer’s terms on your quote.

FAQs for Harlow

Does the Boiler Upgrade Scheme cover homes in Harlow?

Harlow is in England, where the Boiler Upgrade Scheme runs. It gives £7,500 towards an air-to-water or ground source heat pump, or £2,500 towards an air-to-air heat pump that replaces the fossil-fuel heating and meets the whole home’s heating need. We hold MCS certification, so the application is ours to make for you.

Is planning permission needed for a heat pump in Harlow?

It depends on the property. The half-mile around the middle of Harlow holds about 13 listed buildings and structures. Heat pumps on houses are often permitted development, but listed buildings need consent and conservation areas restrict outdoor units facing a road. Where it’s needed, we check with the local planning authority (for Harlow, normally Harlow council).

How long does a heat pump installation take?

An installation takes from a couple of days to around a week, depending on the system and how much of the heating changes. We confirm the timing after the survey, so ring 07833 053749 or use the quote form to arrange one.

Do you look at the job first?

Yes. Photos often do the job for simple work, while bigger systems and repairs that need testing get a visit.

What accreditations do you have?

AirCon Doctor is an F-Gas certified company, with NICEIC approval for electrical work and MCS certification for heat pumps. We’re members of Checkatrade too.

Do you protect the property while you work?

Protection goes down first: dust sheets over floors and anything close to the work. Any drilling is agreed with you first, and we clear up the dust and offcuts when we finish.

Can I fit air conditioning or a heat pump myself?

No, not the refrigerant side. Under the F-gas rules, it must be done by qualified engineers from a certified company, and a new circuit is notifiable under Part P unless a registered electrician, such as a NICEIC approved contractor, does it.

How we price air source heat pumps

Your quote is based on your property. We consider:

  • What state the existing equipment is in
  • The pipe route between the units
  • The electrical supply and whether a new circuit is needed

The price reflects the work, not guesswork. That is why every job is looked at first, and why the quote is fixed before we start.

What we need to know

Photos let us diagnose from a distance. Try to include:

  • A close-up of the unit’s label showing the model number
  • A photo of the consumer unit with the cover closed
  • Wide photos of the room or the existing unit

To help us quote: the address and the type of property, pictures of the rooms or units, the make and model of any existing system and anything you’ve noticed, such as an error code or a noise. Then phone us on 07833 053749 or fill in the contact form.

Do you need air source heat pumps in Harlow?

Homes with electric heating sometimes look at heat pumps as an alternative. A survey shows whether a heat pump suits the property and what would need to change along with whether any grant could apply.

Most people get in touch when they notice one of these:

  • Planning and permitted development questions
  • Questions about the Boiler Upgrade Scheme
  • Working out whether radiators need upsizing

Sizing comes from the heat each room loses on a cold day, not from the size of the old boiler.

What your quote should include

  • Whether anyone has checked the property or the system first
  • Whether the manufacturer’s warranty depends on regular servicing
  • Proof of F-Gas company certification

Our hiring checklist

Homes in Harlow and heat pumps

About 79% of homes in the Harlow area date from 1945 to 1972, according to Valuation Office Agency council tax records, and Census 2021 figures found about 53% of households in terraced houses. Whether the walls and loft have been insulated makes a real difference to the heat pump size for homes of that period. Shared walls keep a terrace’s heat loss down, while gardens next door make the noise check on the outdoor unit important.

Older homes near St Andrew's Methodist Church may need extra checks for planning and heat loss before a heat pump is designed.

What happens on the day

The work area is kept tidy throughout, with dust sheets down and offcuts and packaging cleared up. If we need to drill through a wall, we agree the spot with you first. The visit takes several days for an air-to-water system with a new cylinder, less for an air-to-air system. The more we can see first, the quicker the visit to Harlow.

  1. First we talk through the property and the current system.
  2. Every room’s heat loss is worked out on site.
  3. From those figures we size the heat pump and decide on radiators, cylinder and outdoor position.
  4. A fixed-price quote explains the cost, the grant position and the VAT.
  5. Then it’s fitted, commissioned and registered with MCS.

Before we arrive

  • Let us know where the consumer unit is
  • Make sure we can reach the outdoor unit, or where it will go
  • Mention any parking restrictions near the property

Getting a quote

Photos are the fastest route to a quote: the inside and outside of the property where the work is, plus the rating plate of any unit already there. Add the address and what you’d like done, and simple jobs can often be priced without a visit.
