These are some of our FAQ's

What size is the thermal-earth heat pump?         We recommend that a space of 1 meter square is allowed for the set up of the unit with the manifold. This can be in a garage or an outhouse.

What happens to the waste water?                    The waste water can be drained into the normal soakaways of the house, into a ditch or for rain water recycling.  The heat pump only runs for short periods of time as and when the heating and hot water is required, as a normal gas or oil boiler would. 

Do we need a license to extract the water?        Ground and surface water exemption applies for one's own domestic purposes where the quantity abstracted for this use is less than 20m cubed in any period of 24 hours.  Our 25kw heat pump will only use 8m cubed maximum on the coldest winters day               

How is the heat pump plumbed in?                         The plumbing for the heat pump is all standard plumbing installation.  CAD drawings are available for the plumber and electrician.

What electrcity supply is required?                         All units run on a 3 phase and single phase electricity supply.  The largest in the single phase is a 25kw unit, and we can manufacture any size in 3 phase.                                                                                                                                                       Is it just for use with underfloor heating?               No, we can also incorporate new modern radiators with the use of our geothermal heat pumps, as the temperatures achieved using a water source heat pump are higher.

 

 

 

What temperatures can the unit produce?               On the heating side, we can raise temps to 55 deg C, and on the hot water, we can acheive temperatures of up to 80 deg C.  

What hot water cylinders are required?                  In most cases it will be up to the plumber to decide, his needing to take into account the domestic requirements for the property ie: what size showers are requested, how many bathrooms and how much hot water is required, but a standard hot water cylinder with a hot water return tapping is sufficient.

Why use a water source?                                Thormec uk use a water source for the heat transference because of the higher efficiency that can be obtained. It also ensures that the heat pump is always drawing from a constant source temperature ie: as the water is being pumped from the ground and then put to waste, it always remains the same temperature no matter how long the heat pump runs for.  

Is water from a borehole or spring to cold?           No, the water coming from a ground supply such as borehole or spring will be a constant 10-12 deg C.  This is the same temperature as the ground which is a renewable solar heat and not a subterainian heat.  This allows our unit to run at a very high efficency as the water is a constant temperature and does not drop off.
