Solar Thermal Installation
Solar thermal panels are fast becoming the alternative renewable technology. Heat accounts for more than 65% of the average domestic energy bill and solar panels cuts annual spending.
It reduces reliance on ever increasing National Grid prices and reduce carbon emissions each and every year.
Vacuum Tube Collectors
Vacuum tube collectors now most commonly use a phase change material in a pipe that heats up, changes to a gas and transfers the heat to a manifold where piping collects it and takes the heat to central storage. Older types were similar to the solar trough panels, with the pipes surrounded by the double wall vacuum tubes.
The vacuum tubes virtually eliminate heat loss through conduction and convection. Flat panels lose some heat. This can sometimes be useful to melt snow loads in winter months. Solar panels can overheat, so flat panels are also better in warmer climates, possibly without glazing.
Benefits Of Thermal Energy
- Pumps and controls means genuine zero running costs
- No glycol means no maintenance or level checks
- Simple controls ensures long life reliability
- Direct to tank design means minimal costs to install
- Lightweight install and minimal roof loading
- Eligible for Green Deal & RHI projects
Heat pumps use pipes which are buried in the garden to extract heat from the ground. This heat can then be used to heat radiators, underfloor or warm air heating systems and hot water in your home.
A ground source heat pump circulates a mixture of water and antifreeze around a loop of pipe – called a ground loop – which is buried in your garden.
Benefits of heat pump
- A ground source heat pump (also known as GSHP):
- Could lower your fuel bills
- Income through the government’s Renewable Heat Incentive
- Could lower your home’s carbon emissions
- Doesn’t need fuel deliveries
- Can heat your home and provide hot water
- Needs little maintenance – ‘fit and forget’ technology
Unlike gas and oil boilers, heat pumps deliver heat at lower temperatures over much longer periods. During the winter they may need to be on constantly to heat your home efficiently. You will also notice that radiators won’t feel as hot to the touch as they might do when you are using a gas or oil boiler. Air source heat pumps are usually easier to install than ground source as they don’t need any trenches or drilling, but they are often less efficient than GSHPs. Water source heat pumps can be used to provide heating in homes near to rivers, streams and lakes.
Costs, Savings & Earnings
Installing a typical system costs around £11,000 to £15,000. Running costs will depend on a number of factors – including the size of your home and how well insulated it is.
How much you can save will depend on what system you use now, as well as what you’re replacing it with. Your savings will be affected by:
Your heat distribution system
If you have the opportunity, underfloor heating can be more efficient than radiators because the water doesn’t need to be so hot.
Your fuel costs
You will still have to pay fuel bills with a heat pump because they are powered by electricity, but you will save on the fuel you are replacing. If the fuel you are replacing is expensive you are more likely to make a saving.
R.H.I.S And Grants
ASAP Plumbers has welcomed the Government’s commitment to give financial help to businesses, public sector stakeholders, landlords and home owners who want to switch over to more environmentally sustainable forms of heating.
The Government’s £860 million Renewable Heat Incentive scheme is expected to increase green capital investment by £4.5 billion up to 2020, stimulating a new market in renewable heat. The number of industrial, commercial and public sector installations is expected to rise seven-fold by 2020.
Businesses that install low-Carbon forms of heating such as Ground Source Heat Pumps will be paid the RHI at 4.3p per kW hour of renewable heat produced for systems less than 100kW and 3p per kWh for systems above 100kW in quarterly instalments over periods of up to 20 years.
