An air source heat pump/ air to water heat pump collects and uses thermal energy from the outside air to heat the home.

Our Daikin air to water Heat Pumps can extract heat from the air even when the outside temperature is as low as -25°C.


Ventilation has a huge bearing on the comfort, efficiency and environment fora building and its occupants.

A building therefore will always require a constant supply of air and this can be achieved in a number of ways.


Solar thermal systems basically convert the sun’s energy directly into heat. This heat can be used for heating, hot water production and even cooling.

We can potentially produce up to 65% of the hot water requirments annually from these solar arrays.


Solar photovoltaic systems harness the suns energy to directly produce electricity.

When the suns energy hits the solar cells within the panels the  electrons move towards the panels electrodes within the field and thus electricity flows.

Keltic Renewables can offer a complete plumbing service to all new build houses. Our experienced plumbers will be able
to install a suitable system for your requirements that will maximise efficiency and provide advice on water saving techniques.
