heat pumps
A heat pump is a system used to heat or cool an enclosed space or domestic water by transferring thermal energy from a cooler space to a warmer space using the refrigeration cycle, moving heat in the opposite direction in which heat transfer would take place without the application of external power. When used to cool a building, a heat pump works like an air conditioner by transferring heat from inside the building to the outdoors. When used to heat a building, the heat pump operates in reverse: heat is transferred into the building from the outdoors. Common heat pump types are air source heat pumps, ground source heat pumps, water source heat pumps and exhaust air heat pumps. Heat pumps are also often used in district heating systems.
The efficiency of a heat pump is expressed as a coefficient of performance (COP), or seasonal coefficient of performance (SCOP). The higher the number, the more efficient a heat pump is and the less energy it consumes. When used for space heating these devices are typically much more energy efficient than simple electrical resistance heaters. Heat pumps have a smaller carbon footprint than heating systems burning fossil fuels such as natural gas, but those powered by hydrogen are also low-carbon and may become competitors.
The UK Government has today been told to do better when it comes to Heat Pumps and Hydrogen Boilers.
A watchdog for spending has said that the Government in the UK needs to do more to make green energy heat pumps and other green central heating options more affordable for the UK customers...
Hi
Can somebody tell me if a standard heat source pump installation uses a pressurized hot water tank? Or will the pressure for the hot water be the same as with my oil boiler and water storage tank (gravity-fed)?
So with all the news about heat pumps I just started idly thinking about investigating in more detail. So I came here and browsed a bit and from what I understand heat pumps are just not going to work for me. I have two houses:
Early 1980s, 4 bed detached, copper microbore pipework...
I'm getting so sick of the media and tories plugging ashp's like they are the solution to all our heating needs.
Latest news today, £5k grant towards the cost of replacing a gas boiler with an ashp. What a joke.
Every ashp system I've worked on and installed runs the heating at 40 degrees...
Some positive news.
For anyone not seen, interesting video from Roger B. on the future for boilers vs heat pumps etc. etc.
Includes some more slightly wacky but interesting points like horizontal cylinders and boilers - anyone done one / seen one on hol ?
Was interested also that their...
Can anyone recommend? .... training in heatpumps, books or web links on fault finding said heat pumps and a good place to get some experience- I'm looking to expand my knowledge.
I've done a taster course a few years back at colledge but that info has rusted in the back of my brain.
Hi
Has anyone got any experience of these. I especially need to know how noisy they are from practical experience, not from Db figures which I don't understand. Also how reliable?
It will most likely be an 8KW model to run just the UFH only which is set at around 35 C.
They are cheap, maybe too...
I asked the same question when I registered and got slagged. Plenty of years of development.
I have been involved with heat pumps for a while (2002 my first) combis are not my thing.
Any heat pump engineers on here?
Hi
I'm looking for a heating engineer who is experienced in the design and installation of heat pump systems - potentially for quite a number of commercial projects. If you are experienced in heat pump systems please contact me to discuss further.
The source side would be designed by our...

Hi currently in college studying level 3 city and guilds heat pumps. Currently on the test 'know the requirements to install, commission and handover heat pump systems' which is 77 questions long. All though it's a city and guilds test they haven't provided us with any resources (and apparently...

Hello to all I am thinking of doing heat pumps course but is it worth it is there any call for it I have not see one out there so is the course worth doing yet ?
Hi, My name's Carl and I'm a builder. I'm currently renovating our family home and I'm interested in fitting an air source heat pump. I've got a plumber and electrician who can install it but I'm trying to get some information on Dream air source heat pumps as these are the only pumps I can find...
went today to repair some steel heating pipes in a massive old building. pipes are as rotten as a pear. Customer informed me that they are having the existing heating and rad pipework (which by the way is a one pipe system) linked up to a ground source heat pump. My understanding is that the...
