Sentences with phrase «efficiency air source heat pump»

The main focus for this research project is the integration of a combination space and domestic hot water heating system («combi system») with a high - efficiency air source heat pump to optimize efficiency and comfort.

Not exact matches

«allows the system to reach fairly high efficiencies (300 % to 600 %) on the coldest winter nights, compared to 175 % to 250 % for air - source heat pumps on cool days.»

In the heating mode when the outside air approaches 32o F or less, air - source heat pumps loose efficiency and generally require a back - up (resistance) heating system.

They recommend Vaillant air source heat pumps, having worked with for many years, installing high efficiency boilers and solar thermal systems.

In addition, a high efficiency HVAC system, comprised of an air source heat pump and an energy recovery ventilator (ERV), ensures the house stays warm in the winter, cool in the summer, and provides a constant supply of fresh, clean air throughout the year.

For instance, ground source heat pumps tend to have higher efficiencies than air source units during the heating season due to the relative stability of ground temperatures below certain depths, though air source units — which involve much lower capital costs — have closed the gap in recent years as manufacturers have refined their design, and there is evidence to indicate that space heating demand in many Irish buildings may be peaking in Ireland's frequently relatively mild but windy weather, as the guide to air source heat pumps in Issue 24 of Passive House Plus discussed.

Fortunately, in residential and light - commercial buildings, that's become much easier with the advent of high - efficiency air - source heat pumps (mini-splits).
