3 reasons to choose a heat pump

With a heat pump you can:

1. Reduce your carbon footprint

With a heat pump, around 75% of the energy used to heat your home is renewable.

2. Enjoy low running costs

Heat pump running costs are on par with mains gas, but without the nasty emissions!

3. Future-proof your home

By 2025, fossil fuel boilers are likely to be banned in new builds. Create a sustainable home now.

Reducing carbon footprint

One of the main benefits of a heat pump is their environmental credentials. Heat pumps are a low carbon, renewable technology. Powered by electricity and incredibly efficient, they help to reduce the carbon footprint of your home.

How does a heat pump work?

Intro

An air source heat pump collects energy from the air, even at low temperatures.

1. Evaporator

The energy is absorbed from the air to the refrigerant in the evaporator.

This process increases the temperature of the refrigerant, changing it from a liquid to a vapour.

2. Compressor

The vapour is compressed by an electrically driven compressor, increasing its temperature.

3. Condenser

The condenser releases this heat energy into the water used in your heating and hot water system.

4. Expansion Valve

The cooled refrigerant turns back into a liquid and the process starts again.

Reducing carbon footprint WINNER: Heat Pumps!

There’s no competition when it comes to carbon footprint – heat pumps win hands down. Powered by electricity and designed to make use of the free solar energy in the air or ground, a heat pump can significantly reduce the environmental impact of your home.

Heat pump and boiler installation and running costs

Costs are a key consideration when looking to upgrade your heating system. How much will a heat pump or boiler cost to purchase and install? Are there incentives or grants you can benefit from? And what can you expect the running costs to be? Let’s take a closer look.

Running costs

We’ve taken a look at how much a heat pump costs to run alongside the most common fossil fuel boilers, factoring in the cost of the fuel and their efficiency to compare the cost in pence per kWh.

Installation costs

For installation costs, we are comparing how much a heat pump costs to purchase and install, minus the potential Renewable Heat Incentive payments, against the most common fossil fuel boilers.

Heat pump grants

Although heat pumps initially cost more to purchase and install, easily accessible government grants and tariffs can bring them in line with boiler systems.

The Renewable Heat Incentive (RHI) is a tariff-based scheme that offers quarterly payments to homeowners over a 7-year period – so you benefit from payback and low heating bills.

The newly introduced Green Homes Grant provides vouchers to cover two-thirds of the cost of installing energy efficient or low carbon home improvements. It’s possible to combine both schemes – find out how to maximise the Green Homes Grant when installing a heat pump.

Installation and running costs DRAW: Heat pumps and gas boiler

Whilst a heat pump costs more upfront than a fossil fuel boiler, financial incentives and low ongoing running costs substantially reduce this spend overtime, representing great value for money.

Future-proofing

The climate crisis means that action has to be taken to future-proof the housing stock, ensuring both new and existing homes are more efficient. This focus means that the way we heat our homes is going to change significantly in the next 5-10 years.

Life expectancy

Heat pumps and boilers are both established and well-tested heat sources, but did you know that heat pumps have a longer lifespan?
