How it works

Air Source Heat Pump Installation

Where the property suits one, an air source heat pump delivers several units of heat for every unit of electricity it draws.

How a heat pump earns its cost

A heat pump moves heat rather than generating it, extracting warmth from outside air even in cold weather. That is why it can deliver more heat energy than the electrical energy it consumes — the reason it is treated differently from direct electric heating.

It depends on the building

Heat pumps run at lower flow temperatures than a gas boiler, so they work best in a well-insulated property with correctly sized emitters. In a draughty house with small radiators the result disappoints. The survey establishes whether the building suits one before anybody spends money — and if it does not, we will say so.

MCS certification

We are MCS certified for heat pump installation, which is the requirement for accessing government grant funding where a property qualifies.

The survey does the honest work

A heat pump survey is mostly arithmetic: the building’s heat loss, what the radiators or underfloor system can emit at low flow temperatures, where the outdoor unit can live, and the state of the insulation. If the numbers work, a heat pump is a genuinely efficient way to heat a home. If they do not, we will tell you what would need to change first — or point you at a system that suits the building better.

Suitability

Where it suits — and where it doesn't

Well-insulated properties

Heat pumps run at lower flow temperatures than a boiler, so they reward buildings that hold their heat, with emitters sized for the job.

Homes off the gas grid

Where the alternative is oil, LPG or direct electric heating, the heat pump’s efficiency counts for the most.

Draughty houses with small radiators

The honest answer: the result disappoints. Insulation or emitter upgrades come first, and we will say so at survey rather than after installation.

Paired with solar and battery

Solar PV and battery storage supply the electricity a heat pump runs on — designed together, they bring the running cost down further.

The scope

What's included

  • MCS certified installation
  • Full system design and survey
  • Works with underfloor or sized radiators
  • Eligible for grant funding where applicable

How the job runs

  1. Free home survey

    We visit, measure each room and look at how you actually live in the house. Heat output is sized per room — a guess made over the phone is how people end up cold in the room they use most.

  2. A written recommendation

    You get a clear proposal setting out what we would install, why that specification, and what it costs. No pressure and no obligation to go ahead.

  3. Removal and disposal

    Removal and disposal of old storage heaters, convector heaters, boilers and cylinders is part of the job, and we make good afterwards.

  4. Installation and handover

    We install, test and then show you how to run it. Getting the controls right is most of the saving, so we do not leave until you know how to use them.

Questions

Frequently asked questions

Do heat pumps work in cold weather?
Yes — extracting warmth from cold outside air is what they are designed to do. The survey checks that the system is sized for the coldest weather your area actually gets, not for an average day.
Will my radiators need replacing?
Sometimes. A heat pump runs at lower flow temperatures than a gas boiler, so each room’s emitters need enough surface area to deliver the same warmth. The survey establishes which radiators can stay and which need upsizing before anything is agreed.
Is grant funding available?
Where a property qualifies, yes — and installation by an MCS certified installer is the requirement for accessing it. We are MCS certified, and the survey will tell you whether your property qualifies.
What can I replace my night storage heaters with?
Usually either modern electric radiators controlled room by room, or high heat retention storage heaters where your tariff still rewards off-peak charging. Which suits you depends on the tariff, the building and how you use the house — that is what the free survey establishes.
Which electric radiator is the most efficient?
Honestly, they are all essentially 100% efficient at the point of use — every unit of electricity becomes heat in the room. What varies between systems is control: whether you can heat only the rooms you are using, only when you are using them. That is where the saving comes from, not from any particular radiator.
Can I replace my gas boiler with electric heating?
Yes. We replace gas boilers and their radiator circuits with electric heating and hot water, which removes the flue, the gas connection and the annual gas safety inspection. Electricity costs more per unit than gas, so at survey we will be straight with you about running costs and about whether solar or battery storage changes the picture.
Do you remove and dispose of the old system?
Yes. Removal and disposal of old storage heaters, convector heaters, boilers and cylinders is part of the job, and we make good afterwards.
What areas do you cover?
We are based in Bournemouth and work across Dorset, Hampshire, Wiltshire, Somerset and Devon, and into West Sussex, Surrey, London, Kent, East Sussex and Oxfordshire.
Are you certified?
Yes. Dynamic Heaters is MCS certified, NAPIT approved, RECC registered and an approved Sunamp installer.
Do you charge for a survey?
No. The home survey and the written recommendation that follows it are free and carry no obligation.
Do you work on social housing and commercial projects?
Yes. Alongside private homes we have completed social housing heating and hot water upgrades, including a New Forest District Council project covering sixteen properties, and community buildings such as a village hall in Lytchett Matravers.
