What is air source heat pump?
Air source heat pump is a device that transfers a large amount of heat contained in the air to the space requiring heat by consuming a small part of electric energy.It can provide users with hot water, refrigeration and heating needs. It has large water volume, high water pressure and constant temperature all day. Compared with coal-fired, oil-fired and gas-fired boilers, air source heat pump can help save more than 40% of energy.
The benefits of air source heat pumps
- Lower fuel bills are likely, especially if you are replacing conventional electric heating.
- Possible government grant available
- It could lower home carbon emissions, depending on which fuel you are replacing.
- There are no fuel deliveries needed.
- It can heat your home as well as your water.
- There is minimal maintenance required.
- Can be easier to install than a ground source heat pump.
- During winter, an ASHP 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.
- Unlike gas and oil boilers, heat pumps deliver heat at lower temperatures over much longer periods. If you are installing an ASHP to replace a gas or oil boiler, you should consider whether you can also upgrade your insulation to get the most out of your ASHP. You might also consider fitting larger radiators or underfloor heating.
Is an air source heat pump suitable for me?
To tell if an air source heat pump is right for you, there are a few key questions to consider:
Do you have somewhere to put it?
You'll need a place outside your home where a unit can be fitted to a wall or placed on the ground. It will need plenty of space around it to get a good flow of air. A sunny wall is ideal.
What type of heating system will you use?
Air source heat pumps perform particularly well with underfloor heating systems or warm air heating because they operate at low temperatures. Homes without an existing central heating system will require one to be installed for an air source heat pump to work.
Is your home well insulated?
Since air source heat pumps work best when producing heat at a lower temperature than traditional boilers, it's important that your home is well insulated and draught-proofed to minimise heat-loss.
What fuel will you be replacing?
The system is more likely to pay for itself if it's replacing an expensive system like electric heating.
Heat Pumps are not suitable for all
Costs
Installing a typical system costs around £9,000 to £15,000. Running costs will vary depending on a number of factors including the size of your home, how well insulated it is and what room temperatures you are aiming to achieve.
Savings
How much you can save will depend on what system you use now, as well as what you are 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. If underfloor heating isn't possible, use radiators sized for the application. Your installer should be able to advise on this.
Your fuel costs. You will still have to pay fuel bills with a heat pump because it is powered by electricity, but you are likely to save money on your fuel bills (depending on the type of heating you are replacing).
Your old heating system. If your old heating system was inefficient, you are more likely to see lower running costs with a new heat pump.
Water heating. If the heat pump is providing hot water then this could limit the overall efficiency. You may want to consider solar water heating to provide hot water in the summer and help keep your heat pump efficiency up.
Using controls. Learn how to control the system so you can get the most out of it. You will probably need to set the heating to come on for longer hours, but you might be able to set the thermostat lower and still feel comfortable. Your installer should explain to you how to control the system so you can use it most effectively.
Characteristic
1. The unit uses air as the heat source for refrigeration, heating and high-temperature hot water. Its efficiency is up to 300-500%.
2. Water and electricity are isolated without any pollution discharge. It is environmentally friendly, reliable, energy-saving, reliable and convenient.
3. The unit works around the clock with large water production. It can realize centralized water supply.
4. The system is more reliable and efficient by adopting the method of circulating heating.
5. Refrigeration, heating, haze removal, floor heating, comfort and energy saving.
Performance Introduction
a. The machine can run heating, refrigeration, hot water, refrigeration and hot water, heating and hot water operation modes.
b. The motherboard can set model parameters.
c. It has multiple temperature sensors to ensure detailed and accurate sampling of the working state of the machine. All temperatures can be queried and displayed on the main controller.
d. Each compressor has high-voltage protection, low-voltage protection, exhaust temperature protection and current overcurrent protection to ensure reliable operation of the machine
e. Efficient and accurate electronic expansion valve control algorithm.
f. Lack of phase and wrong phase will cause the whole machine to stop running.
g. The waterway has safety measures such as waterway switch and low-temperature antifreeze protection.
h. Real time timing switch function.
Compatible with different kinds of terminals
In the air source combined supply system, the indoor end system includes fan coil, low-temperature radiator, floor heating, etc.
Fan coil can be used for refrigeration and heating, and the heating comfort is poor.
Radiators and floor heating are only used for heating.
The best combination is fan coil refrigeration in summer and floor heating in winter
