Further to an earlier post. If I buy a cheap Dab or Wilo pump would it be noisier than a new grundfos? The pump is right over my lounge (bungalow) so this is an important issue to me. Thinking of changing to system boiler in the spring so would like to keep cost down on pump.

I'm going to replace a very aged boiler in the spring. Currently have fully pumped, vented system. As a rule of thumb and assuming my pipework is OK would I be best to upgrade to a system boiler or stick with a like for like regular boiler. I'm asking now because I'm going to change the...

After my previous posts I'm going to change the pump (Grundfos 15-50). Went down my Mums and looked at hers and it sounds and feels different, as though it is actually working. Mine just humms and has a mellow vibration, hers feels like it's pumping. I have 8 rads in bungalow and 6 have TRV's...

I know I've had other posts about my system but this is a fairly straight question. If a pump is slowing down or not working will the CH and DHW either work or partially work as though on a gravity system or would the rads fail to heat at all. I'm seriously thinking of getting a new pump...

Hi, Further to an earlier similar thread I hope someone can help resolve my CH issues. To start with does anyone recognise the TRV below and if so do you know how to get the TRV head off? Further to the rest of my original post, below, could it be these TRV's that are only...

hI Already posted for help after having a boiler airlock which is now OK. I have a 30 year old system (fully pumped - vented CH) with a 17 year old boiler and suffer cold bottom rads (2 x 2200mm double each with saucer sized warm areas in top corners and that's it, all others as bad)...

Hi Further to my other post I have a specific question about an airlock. My rads are all fully bled but the boiler flow and return pipes sound empty. I have had the pump running for several hours (boiler off) what should I do now. I can't seem to find anywhere else in the loft to bleed the...

I drained my system down today and refilled with Fernox Heavy Duty Restorer because of cold spots in the bottom of all rads. I've bled all the rads and ran the system for an hour or so with the heating off. However, when I ran the heating up the boiler dropped back to pilot only and wouldn't...

Hi again, I can't decide whether to get a Mira Magna or Aqualisa Quartz (pumped version either way) and have swotted on the specs and flow rates till I feel like going dirty instead. Aqualisa gives an extra 2 litres per min but Mira's 16lpm should be ample? I've never had a power shower before...

Hi all. I am about to fit a 900mm stonecast quad shower tray. It''s the type that comes with legs (merlin) for raising it on concrete floors for the waste. Do I install it on the legs alone or should it also have a concrete bed under the main part of the tray to spread the weight too?
