just in the process of completing the installation of my ground source heat pump! it's been over 18 months in the planing stages, talking to people or should i say trying to talk to them? it seems that they all want to fit you a system for a very large fee or to just tell me to get lost, is it really a ground source mi5 out there?.
but for all you guys out there looking at fitting a system so far fitting it its not been that bad! during the 18 months i've talked and trodden on a lot of toes of a lot of fitters and suppliers but i think it will all be to my advantage in the end, took info from them all wedeled out the bullshit and off i went, the heat pump i'm fitting is a IVT E7 with over 1100m of ground collector pipe in 4 loops in a system of my design i've called vinkys, taking the rayhoue helix design and making a simular design out of mdpe, this is 3 vertical coils in each loop, each vinky is 75m of 35mm mdpe pipe coiled in 1m diameter loops about 2m tall, got a brilliant digger driver who dug all 12 4m deep holes and the adjoining trenches in a 8 hour day costing me £350 hire for digger and driver, although i've enouth ground to of used slinky's it woud of ment ruining a established garden and posibly geting into the ceptic tank and outflo area?
one of my main concerns is freezing the ground as the person i purchased the heat pump from had just that happen to them thus they was forced to sell the pump, there ground collectors were in the front garden and during the cold spell at the beginning of the year they returned from holiday to find the water board diging the road up outside the front of there house, the pump had not only froze there garden and drive but also permutated out into the street and froze the main water pipes to the rest of the road!, to hopefully stop any freezing of my garden i've put another loop of 100meters of 25mm mdpe pipe between the tiles and felt on the roof to back feed warm solar heated water into the ground loops thus recharging the ground, as one person said u must use the ground as a battery the more you can recharge it the better the pump will work, also down one vinky i have a tube where i can drop a temp sensor to see what the ground temp is at any time of the year ,oh it was 17c at 4meters in september during the dig!
over the next few weeks i've got to get the tails from the garden into the house connected to the pump and the collectors filled, but at the moment with the bad weather they are under a preasure check of air at 2 bar
i know im not the first to install a heat pump but would just like to put minds at rest of others who are thinking of fitting there own system and i think there may be a few ideas in the above read, i have some photos if you would like to see the project so far?
