Imagine never having to worry about turning your heat controls down to save money. Imagine your home being constantly warm and comfortable. Imagine a heating system that uses renewable energy, requires no maintenance and is completely safe. We can help you achieve this please read on.
There are three main types of heat pump
GROUND SOURCE HEAT PUMP
Ground Source Heat Pumps have a pipe buried in the garden. Within the pipe circulates a glycol/water mix which gently absorbs the heat stored in the ground. This low level heat is concentrated and transferred by the Heat Pump to the wet central heating system within the house.
AIR SOURCE HEAT PUMP
Air Source Heat Pump does not have a ground loop, but instead absorbs the heat from the air. Their advantage no digging required, however they are slightly less efficient and their siting needs to be sensitive due to the small amount of noise from the external fan.
AIR TO AIR HEAT PUMPS
Air to Air Heat Pumps as the name suggests absorbs heat from the air outside and concentrating it to a much higher temperature then moves it inside the house distributing it via the air through a heater or chiller when in air conditioning mode. They are highly efficient and are ideal for small open plan dwellings. The air to air is not a solution for hot water but does give air conditioning during the hot periods.
SUMMER COOLING FROM YOUR HEAT PUMP
By adding a unit into your loft you can provide an effective summer comfort cooling. The unit draws hot air from the house, takes heat out and returns the cooled air. The heat is fed into the ground loop via the heat pump and stored in the ground for later use.
ALL ABOUT GROUND WORKS
The ground works are a vital part of any Ground Source Heat Pump installation. Here at Steve Cross it is our intention to find the best solution at the lowest cost to the client. The options vary depending on the amount of land and budget available.
Ground loops consist of a series of pipes buried in the ground at a depth of one metre. The ground temperature at this depth is fairly constant between 7 - 13ºC throughout the year. The heat pump uses a ground loop (pipe) with a water water/glycol mix to capture some of this heat. There are two main types and the one to use is dependant on the amount of land available.
Straight Ground Loop
Slinky ground loop
The patented compact collector allows a ground loop to be used where space is at a premium. The collectors can be buried flat to reduce the depth of the earth works or vertically to reduce the area needed for the panels
Bore holes offer a solution where very little land is available. A vertical hole is drilled to a depth of 50 – 80 metres through the rock underneath the garden. The collector pipework is inserted in the hole to the full depth and connected to the heat pump.
Streams Rivers and Lakes
This option also exists to bury a pipe on the bottom of a lake or river to collect the heat.
