Simply put an Air to Water Heatpump is like your fridge in your kitchen but in reverse, it produces heat instead of making cold. It is run by electricity and comprises of a unit that looks very like an air conditioning unit that sits in your back garden.
Connected to this unit are 2mm x 32mm insulated pipes running from the outdoor unit to the indoor cylinder unit (Monobloc system). These pipes bring hot water to your heating system and your hot water system.
Now for the technical part, how does the Air to Water Heatpump make this heat? Believe it or not there is enough heat in the air down to -25 degree’s for the heatpump to supply heat into your heating system. This is simply how the Heatpump does this:
Green-house have recognised that in order for a new build house to meet the strict Part L building regulations a new build house has to have some Renewable energy helping the house’s energy requirements. Builder’s basically have 2 options:
We feel the best option for a new build is an Air to Water heatpump system. it provides maximum levels of comfort and the cheapest running costs, in fact it’s a “no brainer”. Its also an extremely simple system for the end user to live with.
A new build house needs to be a minimum of an A3, this means the house has very low heat loss. We set up all our heatpumps to run 24/7 meaning you always have a warm house and always hot water.
The heatpump complex controller will look after everything. All that required from the homeowner is set their thermostats to their desired room temperature ( design temperatures are 21 degree’s for living areas, 19 degree’s for bedrooms). The air to water heatpump can provide this level of comfort very cheaply, approx. €400 for 150 sqm new build house.
Heatpumps are suitable for the majority of renovation / retrofits in the modern era of building, but every house is different. A heatpump is very different from a standard gas boiler system,a heatpump supplies water to the heating system at 30 – 45 degree’s but for longer periods, where a gas boiler supplies hot water at 60 – 70 degree’s in short bursts. The best gas boiler on the market is 97% efficient, where our where our Nibe F2040 is 413% efficient. This allows us to give the Heatpump a license to run 24/7. In a new build this is suitable, but obviously a retrofit is different as the heat loss will more than likely be far higher.
Here at Green-house we do a full design and survey of the house and heating systems (radiators or underfloor) to see if the heatpump will be a suitable system to provide the maximum levels of comfort and cheap running costs.Usually houses with Underfloor heating are suitable. With radiator systems we need to make sure that the radiators are sized to work with the heatpump. after we have established this we need to look at getting a comprehensive BER done on the property to fully ascertain if the Heatpump will work effectively.
A full review of the heating controls is also needed to tailor the system to the house its heating. Building and insulation standards have been raised in Ireland in the past few years and we are finding that most retrofit projects are Heatpump compatible, in fact the savings versus gas / oil are far higher in these projects, usually 60% cheaper than oil & 40% cheaper than gas!
We offer fully designed, bespoke energy-efficient heating systems to installers, builders, contractors, architects and self-builders nationwide. We have the largest renewable energy showroom in the country in Deansgrange, Co Dublin.
From our vast experience we know that Every home and Family have different requirements, greenhouse recognise this and tailor our Renewable heating systems to match your needs and to ensure maximum comfort while delivering the most efficient system. We like to think we design, install and back up our Renewable systems treating the process as if it was our own home and not just a client’s project.
