Hello,
We were due to have an air source heat pump installed on a grant scheme on Monday, with radiator size upgrade, but retrofitting using the existing pipework.
The calculations have been done to show it's viable etc...
However their engineer has just (!!) looked at the photos taken by the...
I have a head height problem for the storage tank and needed a solution that would allow the monobloc to heat from the bottom of the tank
I have now sorted the issue with 2 tanks in series, both single coil
The smaller one has solar heating and this then provides cold, warm or hot water to the...
I’ve had a Viessmann ASHP fitted. Fan noise outside is v low- we do not notice it. Inside though, the joules cyclone unvented cylinder seems to be making a constant whine. At first I thought it was the Vitocal 200 boiler beside it but I am pretty sure it is the tank? It is all new ( April) and...
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...
Interested on thoughts on this (I've also posted on another forum but thought this might be a better place to ask);
Long time lurker, have gleamed some great knowledge from this site, finally signed up as I cant find an exact answer to the below. I'm not a heating engineer, but an electrical...
Hi. Hopefully someone can point me in the right direction. Bit general. We have solar boosting our hot water using iboost. My question, the current immersion element hasn’t been changed for 14 years. Should I upgrade/change it to increase efficiency? Current I haven’t seen any degradation in...
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...
Nibe ASHP alarm code 005 low pressure warning, anyone know the cause?
Hello, I hope someone can give me some advice on replacing an old air source heat pump.
We moved into a shared ownership house last year which has a Daiken air source heat pump fitted to provide heating and hot water. The unit was fitted when the house was built 12 years ago. It seems that the...
I’d like some advice and opinions please.
I have a 150 year old stone cottage ( 2 foot thick solid stone walls) some roof insulation and double glazed windows in a very cold exposed hill top position in the north western Yorkshire Dales.
we are planning to put underfloor heating downstairs and...
Hi, Our church is consdering replacing our old gas boilers with modern condensing ones. We would like a hybrid system involving the use of an ASHP. Two of the contractors that have supplied quotes for the work have suggested that we wait for a while on the ASHP as the prices are falling...
Just wondering if anyone has even seen an issue with the pressure gradually increasing on a closed loop system where there is no fill loop attached. I'm seeing this issue on a gshp and whats more unusual is its on the cooling side. If it was on the heating side you could put it down to expansion...

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 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...
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...
Hello
I had a solar thermal installation. However, the Gledhill Stainless Steel Lite keepings making popping noises. Anyway, I was looking to have it replaced with another cylinder and found this one: Gledhill SunSpeed 2 Open Vented Indirect Twin Coil Solar Cylinder | Vented Cylinder -...

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?

Hi,
I have a question about my s plan heating. I have a Worcester 35cdi erp boiler connected to 2 heating loops and an unvented indirect cylinder via 3 switch values. If I have the radiator heating on and water heating on the system doesn’t close the heating or water switch values. So doesn’t...
Hi all. I have an Isoflo CL170 cylinder with good few years life left in it in my system which has performed trouble-free other than the odd new immersion element. I'm getting a new ASHP fitted and the installer is recommending scrapping the Isoflo and replacing it with a Secon Trade Heatpump...
