What is a Heat Pump?

A heat pump replaces traditional oil and gas systems. The heat pump generates the heat that will heat your radiators or under floor. Heat pumps run on electricity. However, they are very cost effective to run. On average for every kilowatt of energy you pay for you get 3 from the heat pump.

Our heat pumps meet 100% of all the heating and hot water needs of the houses.

How does it work?

There are 2 main types of heat pumps. Air-to-water and Ground Source Heat pumps.


This heat pump works by taking the heat from the air, (it works at -20 degrees) and feeding it through a compressor and this compressed gas is what is used to heat your home and hot water.

Ground Source:

This works similar to an air-to-water except it takes its heat from the soil rather than the air. This can be done by drilling a hole straight down into the earth or by digging out an area and laying the pipes horizontally.

New Build

Your heating system is one of the most important decisions you will make when building a new house if not the most important.

Design is the key element to consider when choosing your heating system.
This is due to the way the house is designed.
2 houses can both be 200m² but they can have very different heat demands. Some of things that we take into consideration are:

  • How much glazing is in the house?
  • Your level of glazing?
  • Your insulation levels?
  • Where you are building your house?

We can gather this information from the XML file that your BER assessor will have.
This XML file contains all the elements of how your house is going to be built.
We use a software called a Heat Pump Calculator (HPC) where we input all the details that are specific to your house and are able to project what your yearly running cost will be.
We will also be able to use this software to correctly size your heat pump as it will be tailored specifically to your house only.

We have a network of trained installers throughout the county that we can arrange to meet with you on site to discuss your project in further detail or we can arrange a meeting with one of our technical engineers.

Case Study

230m² New House

Ashgrove Installed the following:

  1. An 11kw Air-to-water heat pump using underfloor heating on the ground floor with radiators on the first floor.
  2. Mechanical Ventilation with Heat Recovery

Low Energy appliances and lighting was also installed throughout the house.

The total household Electricity bill is only €1350 per year and that includes all the appliances as well as heating.

“Immediately we were impressed, after presenting our plans to Ashgrove, they coordinated with our builder throughout the installation. Substantial annual savings have been achieved now and into the future with the added benefit of using a clean environmentally friendly system”

G.McCarthy, Co.Cork

Existing House

The Benefits of Changing to a Heat Pump:

  • Low cost constant heating
  • Low cost constant hot water
  • Use your existing radiators or underfloor heating
  • Intelligent automatic controls
  • Online control and monitoring
  • Increased comfort level

If you don’t have plans of your house then we can arrange for one our trained installers to visit the house and they will be able to advise you on which system would be best for your needs.

Heat pump technology replaces the traditional oil or gas systems and it can be connected to your homes existing radiators or underfloor.

We have a network of trained installers throughout the county that we can arrange to meet with you on site to discuss your project in further detail or we can arrange a visit in our office with one of our technical engineers.

Case Study

318m² Existing House

Currently being heated by oil boiler with underfloor heating

It was retrofitted with an air-to-water heat pump from Ashgrove and the client was still able to use both his existing underfloor heating on both the ground and first floor

By using an Ashgrove system they were able to save €3,034 per year!

We hold Information Events during the year throughout the country.

At these events you will get the opportunity to meeting our engineers and installers face to face to discuss all of our questions.
The event will begin with a 1 hour presentation by one of our engineers. We will then take you on a short bus ride to heat pumps that have been installed in the local area.

Tea and coffee and light refreshments are provided.

If you wish to book a place at our next event please fill in the contact form below.
