Ground Source Heat Pumps
Ground Source Heat Pumps use energy stored underground from sunlight. The pump withdraws energy from the ground through a collector buried 1m below the surface, or inserted vertically into a bore hole.The most difficult part of fitting a ground source heat pump is the insertion of the collector in the ground. In order to offer an efficient and quality service we have invested heavily in our groundworks division. As well as trenching machines and diggers, we operate a purpose built borehole machine which is ideal where land is limited.
Air Source Heat Pumps
Air to water heat pumps use the outside air heated by the sun, so there is no need for boreholes or pipes in the ground. These types of pumps are ideally suited to existing dwellings where digging up ground is not an option.Exhaust Air Pumps
Heat recovery based on exhaust air is a way of combining necessary ventilation with energy normally wasted by the exchange of air within a building.Heat recovery heat pumps reuse the energy from exhaust air for heating hot water, creating a complete heating and ventilation system contained in a unit the size of a fridge freezer. These units, which give a healthy and comfortable form of heating are ideally suited to apartments and small houses.
Collectors
The collector we supply is 40mm x 2.4 PN 6.3 PEM pipe, specifically manufactured for geo-thermal ground collectors. The length of the collector varies depending on the ground conditions and on the heating system, i.e. radiators or floor heating. Maximum length per collector must not exceed 400m. Where there is more than one collector, they must be connected in parallel, with means of adjusting the flow. The collector is supplied so no joints are required in the trenches, any joints must be accessible. If a manifold is supplied, this can be installed inside the building or in an inspection chamber outside the building. The collector should be buried a minimum depth of 1 metre and the distance between collectors, should be 1 metre. To join the collector from the manifold to the building we recommend and supply pre-insulated pipe which avoids potential freezing problems. Our groundwork division can carry out all of the groundwork and the installation of the collector pipe. Should you wish to carry out your own groundwork we are happy to offer advice and can, if required install the pipe and pressure test for you.Underfloor Heating Systems
We will undertake most commercial or domestic underfloor heating projects, no matter how large or how small, anywhere in Great Britain.Equipment
PIPE We use 16mm x 2mm multilayer PE-RT pipe with two layers of polyethylene pipe, a layer of aluminium pipe (which is the oxygen barrier) and two more layers of polyethylene pipe. This pipe is among the most effective types of pipe for underfloor heating and it has a heat output 30% greater than PEX pipe. To get the same heat output, PEX pipe of 20mm would have to be used. Due to the fact that the pipe is 2mm thick and has an aluminium layer, it transfers heat very quickly and consequently heats the room faster. The pipe has an operating pressure of 10 bar maximum and a working temperature up to 70 degrees C.
MANIFOLDSThe heavy brass manifolds are made in Italy and come pre-attached to mounting brackets and vibration absorbing clamps. They are nickel plated and fitted with two purpose control/balancing valves and are fully assembled, leak-tested and packed. The supply and return manifolds are each fitted with an isolation valve which includes a temperature gauge and a purge/vent assembly. The control valves are designed to take standard actuators.
CONTROL PACKA pre-assembled manifold control pack which has been designed for quick assembly on to an underfloor heating manifold providing an integral thermostatic mixing valve and pump which gives excellent temperature control.
ELECTRONICSAs part of our normal supply we include the full electronics package required to run the underfloor heating system. For each manifold we supply a wiring centre, actuators for each loop and surface mounted thermostats for each room. While we supply the electronics package, we are not qualified electricians and our scope of installation ends at the manifold.
DESIGN - upon confirmation of order, we produce a computer generated design of the underfloor heating system for your project, which will be forwarded to your for approval. This will show the design layout of the pipes, the length of each individual pipe run on each manifold, air changes, heat loss, heat output and U values for windows, doors, external walls, internal walls and roof.
INSTALLATION We have our own installation teams who travel anywhere in Great Britain to undertake project installations. At no additional cost, we will start early, finish late and work over weekends and public holidays if necessary to meet deadlines. We take health and Safety issues very seriously and have our own Health and Safety policies. We strictly follow all site procedures and our installers always carry a First Aid kit with them. We connect the underfloor heating pipes to the manifold, pressure test each one of them and leave the pipes under pressure with a pressure gauge attached to the manifold so that you can check during the screeding that no damage has been done to the pipe.
