    WBA or PVA ?

    gonna give the walls the once over with a floor scraper, then probably get some wickes stuff. Ive heard blue grit and plasprime are pretty good and work out about £5 dearer than wickes stuff. The thistle stuff ive seen for £50 a tub, so bit too pricey

    Harling trowel?

    Need to do a small patch up job on some pebbledash that's blown. Question is how do I get the spar on the new render? Do I need a Harling trowel or is there some cheap gizmo I could knock up? Don't really have use for a Harling trowel. The patch job is approx 4m2.

    Would leaving boiler on all day increase bill?

    Well blimey! Thankyou everyone who participated in this post. Some very interesting points made. It will be interesting for future reference to see how much +/- the bill is. We normally leave both the CH & HW on continuously and use the room stat to switch the CH. However due to the buzzing...

    Would leaving boiler on all day increase bill?

    I did ask the plumber/engineer if he is gas safe registered and he said he is. I didn't ask to see a certificate, perhaps I should have. Don't mean to offend any tradesmen, but there are tons of plumbers that also install and service boilers and are registered as gas safe engineers. I don't know...

    Would leaving boiler on all day increase bill?

    It's an ikon 40-50 boiler. Plumber been round and has suggested it's the programmer, the gas valve or a solenoid on the pcb. He said he couldn't source a new pcb for it. Was serviced last December and hadn't missed a beat. Recently had to replace a zone valve cos water was scalding all the time...

    Would leaving boiler on all day increase bill?

    Having a problem with boiler buzzing when heating is switched off. This only stops if I leave the heating on. Turned all the rad valves down now its a bit warmer and switch off the boiler(ikon) when going to bed. Would this increase our bill? I've heard that leaving it on is probably...

    Zone valve replaced but now boiler buzzing

    I had a problem with the hot water where the valve was knackered so the plumber came and replaced the valve. That issue is well and truly resolved. Now the boiler is buzzing away when the CH is switched OFF, this buzzing has never happened before. Plumber came again yesterday and isolated the...

    water too hot checklist

    Plumber has changed valve and that seems to have sorted it. But now the boiler is making a banging noise whenever the heating is switched off. Could this be air in the system, post valve change? Plumber said he'll have a look tomorrow. Boiler has never made any weird noises before.

All pipes and cylinder now cool totouch, turned it all back on again and the boiler fired up more or less simultaneously. I set the temp on the cylinder stat to between 60 and 70deg. There...

    water too hot checklist

    I turned the whole lot off using the isolator spur and left it for well over an hour. Switched it back on leaving only HW on at the programmer, sprinted downstairs to the kitchen to see if the boiler had fired and it HADN'T. I turned the hot tap on and sure enough the water was still scalding...
