    Air source heat pumps in the news again

    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...

    Unusual large water tank, considerations

    Hi Guys I'd like your thoughts on this. Customer has a 3 bar whole house shower pump and also an aqua lisa digital shower. Upon replacing the pump I noticed the water tank is only 50 gallons. It really should be 80-100 gallons? Its a 3 story town house with basement and two bathrooms...

    Old Viessman vitodens 100 combi problems

    Hi guys, Just replaced some radiators in a recently purchased student let. The boiler is a 12 year old vitodens 100, 7248589. I tested the heating and hot water before draining down and it seemed to be working, maybe a little lack lustre on the heating. After completing the rads, refilling...

    Faulty new Honeywell valve?

    Hi guys just exploring a possibility I’ve replaced a 3 port valve and it’s passing into the heating circuit when hot water is on. Could an electrical fault cause this problem? There is no call for heat on the heating circuit, proved with my multimeter. The heating pipe work next to the valve...

    Flow gauges for central heating pipe work

    Whilst installing a new heat only boiler today I thought why don't we have flow gauges, in litres per min, on the flow immediately after the pump and then on the return near the boiler? This would allow us to see in real time the performance of the pump and the loss of flow around the system...

    European / international water heaters, no expansion vessel

    I've seen and heard about this a couple of times. When installing an un-vented water heater some parts of the world seem to fit an expansion valve and just allow it to blow off each time the water is heated. No expansion vessel is fitted on the incoming pipe work, they either fit it to a...

    Gas boilers scrapped by 2050?

    Just heard on the news about the Uk's ambitious climate change targets, of which one of them was to scrap gas boilers by 2050. On one hand its 30 years into the distant future but on the other there's still the question of system design, as I understand it new boilers, air source for example...

    Combi or unvented, which is cheaper to run

    Interesting thought I currently have a 28kw combi, 1 bathroom, 2 up 2 down semi. I'm g3 and gas safe. I fit unvented and replacement boilers all the time. I'm thinking about replacing my combi with a small 120 litre unvented cylinder in the loft. An unvented cylinder usually draws about...

    Hi I'm Gsr by the way and should get around to sending in my card details. I'm working on a system boiler and central heating system and the prv/vessel has recently failed, I'm finding it difficult to source the prv short notice, I'm thinking of capping the Prv inside the boiler or the...

    Crosswater brand new shower not hot enough

    I have a customer with a crosswater wlbp1501r+ concealed mixer, it is literally months old. Right from the start they have had "not as hot as they would like" showers, I've calibrated the shower to be as hot as it can possibly be, we still couldn't get the temperature above the 40 degree mark...

    Hi I'm working on a bathroom with some unusual stuff. They picked up an old basin, belfast ceramic style, small about half the size of a standard belfast sink, quite shallow. They think it was from an old chemistry lab... The diameter of the hole measures 80mm but someone has fitted a black...

    22mm Low pressure Check / non return valve, shower pump problem

    Hi Anyone know where you can get a 22mm low pressure non-return valve, it was suggested by Grundfos to combat the pump turning on when a hot tap is used... I've already put a U in the pipework coming off the essex boss. The pipe work is a little strange, it comes off the top of the cylinder...

    Undersized, un-lagged water main in a cellar

    Hi I'd like your opinion on this poorly installed water main, its fitted in a friends cellar. The old pub and bookies was recently converted to 4 flats and 1 terraced house. The main is certainly unclipped and un-insulated but is it undersized? For a start I would prefer 5 separate T's...
