Hydronic Heating Boilers

Hydronic heating boilers are the part of a hydronic heating system that heats and pumps the water. When the thermostat senses that the temperature has dropped it will call to the boiler to turn on and heat the water that is being pumped continuously around the circuit. The cost of running the hydronic heating boiler is your main on going running cost. A high efficiency condensing gas boiler is the best choice if you have natural gas or access to LPG due to the lower upfront cost as well as ongoing running costs.

Gas Hydronic Heating Boilers – High Efficiency

A high efficiency gas hydronic heating boiler will increase your savings on running costs. They improve the efficiency by using the usually wasted heat within the expelled gases to assist with the heating of the water. The cost of upgrading to a high efficiency unit is recovered in running cost savings over 1 – 2 seasons.

Immergas Audax High kW Heat Pump

Electric Heat Pump

An Electric Heat pump is the choice for those who are looking for an electric option that is cheap to run. A heat pump is has the cheapest running costs compared to all other forms of hydronic heating water heating units. A heat pump running costs can also be offset by having a solar energy PV system installed. A hydronic heating system requires a much larger heat pump than domestic water which makes a heat pump a large upfront cost. A heat pump can add around 10K to a hydronic heating system over and about the cost of a gas boiler, and they produce far less kW’s. Heat Pumps are ideal for slab heating but can’t produce the water temperature radiators should be run at. While panels can be used, due to the lower water temperature we need to double the width of each panel. Most hydronic heating systems require more than 15kWs which would mean the requirement for 2 heat pumps.
