We've been using borehole geothermal for 2 years in an 1800 sq. ft house with ufh downstairs only. There are radiators upstairs but as the house is designed with an open landing the rads. are rarely used. We also have a wood pellet stove for additional space heating. We also have a heat recovery ventilation system which helps keep the house ventilated without losing heat.
Overall I would say that it works for us, although there have been a few hiccups. Our house is designed to make the most of solar gain and insulated as tightly as we could. Our bill for the year including water, heating and general household usage comes to about €1200 max. The temperature averages 20 degrees in the winter and warmer obviously in the Summer.
Install solar panels if you can afford it, we still have to get around to this and it will help reduce bills further.
The HRV was about €5,000 and the geothermal was approx. €10,000 - including drilling.
The heating was off for nearly 6 months this year so the bills come out at about €1200. Like I said this includes all electricity usage for a family of 5.
I have a ground source heat pump for three years. With the collector pipes buried in the ground. My heating averages at most 900 a year (using todays electricity prices) and h/w 300 a year (based on the minimum the night-rate could be doing - 1/3). The heating is off from March to October, but the h/w is the annual figure.
180 sqm house. Rationel double glazed windows (so good, but nothing special). Rockwool and bubble wrap in the walls (timber frame). A log stove in the living room. Big windows to the south which helps on sunny days, but really sucks the heat out on days like today with a cold wind.
I wouldn't use the guy I used to also do the house plumbing! I also wouldn't use him to do the Geo again!Thats good.
Would you change anything if you were to build the same house again?
How much was the installation of geo and UFH?
