Good Afternoon All,
This is my first time on the renewables forum so please forgive my ignorance. I've been interested in ASHPs for about 15 years but have always doubted their economic viability - especially for retrofits. Now that there will be no gas connected to new builds in 4 years I am...
I had a solar thermal cylinder installed last week.
The installers had an issue with one of the valves and installed a 15mm pipe (see red arrow in picture) instead of the 22mm at the valve. Is this going to be an issue?
The 15mm then feeds into the larger 22mm. However, my concern is that...
Hello. I’m looking for some advice. We had a 1960’s bungalow in Cornwall with a wooden suspended floor. The old oil builder is 20 years old and so we want to replace it. We were looking at a Air Source Heat Pump with underfloor heating but the more we look at it the more concerned we are that it...
I had solar thermal installed recently, the system is a viessmann and goes with our viessmann boiler. The controls are on the boiler, seems to work well.
I spoke to viessmann technical after the install and they and the install advised to change the water heating from the boiler to only come on...
Hi everyone, this is my first post. I've recently purchased a home where the prior owners have had some sub-standard work done in the past.
The pipework in the photos is the hot water feed from the solar panels down to the hot water tank. It looks like the copper pipe has been routed quite...
I'm an end user with limited knowledge of plumbing and just trying to get an understanding of options available to me. We currently have a Valiant Combi Boiler Sealed Unvented Heating system. It was installed 3 years ago and works perfectly well for both CH & HW. Recently we built an...
I'm planning to get an air source heat pump (ASHP) installed and I'm considering my options about the location of the water cylinder as I live in a small house and space is a premium. I was thinking about building a small insulated shed about 20 to 25 metres away from the house to put the...
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.
We are building a new 2 bed bungalow and looking at Heating / Hot water options. Although Gas is available we are keen to not have it connected but we will be having a large solar system installed as we have a long South facing roof.
Our house that we are moving from has Air con installed in...
If my mates in the Electrician's Forum see me in here, jus' tell I got lost, alright ;)
So, I was called out to the home of a good client. They have a thermal solar installation but were not completely clear of the difference - hence calling in a sparky and I was interested as to how thermal...
Hi, I'm looking for someone to help specify, and possible install hybrid system. Initially the bungalow was setup for all low temp (underfloor heating and Fan assist heating rads), but couldn't afford ASHP at the time, so fitted a Vaillant Ecotec Plus 937 Combi as the heat source. Now looking to...
Had a email today that maybe of interest to some of you?? Kop

Hi, I have a log burner and oil fired boiler feeding into a 'dunsley' neutralizer tank. The system (gravity fed) has worked fine for a number of years, except that it can take 20 to 30 minutes for the rads to get hot first thing in the morning and burns a lot of oil in the process.
I am thinking...
Hi everyone,
I am qualified to work on unvented cylinders but have no experience with solar panels. I have a customer which has a leaking unvented cylinder with solar coil attached.
am i legally allowed to replace the cylinder,is their regulations with solar?
if so, is it easy to drain the...
Hi all.
Does anyone know of a small water heat system that I can attach directly to the back of my log burner, in my living room, that can conduct the heat (by contact) of the log burner and flow the hot water to a panel radiator in another room (e.g. conservatory)?
I only want a very simple...

In my new high efficiency house, I will have UFH with an Air to Water (A2W). Heat pump Monobloc, but for extra cooling on hot days I think extra air cooling with FCUs is needed:
Should I use a secondary Air (to coolant) to Air system, or stick with just the Air to Water system to also drive my...
Hello,
So I want to add a solar thermal system to my existing Worcester bosch greenstar but don't want to lose the functional benefits of the combi boiler.
I'm proposing to install the solar collector on the side of the house in a position that will enable gravity flow to a 200litre tank just...
HI everyone,

Nibe ASHP alarm code 005 low pressure warning, anyone know the cause?
Hello all, I should start off by stating that I'm not in the industry - I'm just a DIYer with a "what-if" idea.
Hybrid systems and solar diverters are nothing new, but as far as I can see the current hybrid systems all require a change of boiler and I'm going to propose a system which could use...
