I have two separate HW cylinders, a long way from the boiler programmer for wiring stats or using RF stats, but they are both within range of our wifi /wireless network connection. Programmer is also within range of the wifi. I would like to set the cylinders up with wireless stats that will...

//media.diynot.com/121000_120756_94609_21610927_thumb.jpg Please excuse my complete lack of protocol in this diagram. What this does is as follows: CH and HW at the top refer to 240V outputs from my heating programmer. The CH and HW outputs go through relay switches which are...

I have a Honeywell V4043H (normally closed) motorised valve in my system. I can see how to wire it into my Corgi programmer so that it will close when the heating goes of or to wire it so that it closes when the hot water goes off. However, I only want it to close when the heating and the hot...

Hello, Planing a new small wet heating system with a mid point valve, 4 radiators and one indirect HW cylinder. All on the ground floor and within a property no bigger than 15 x 15m. I plan to have separate 22mm primary flow pipes for the CH and the DHW, but to have a shared return pipe for...

Yes, copper is best and I would prefer to use that but I also don't want to rip up my beautiful floor and flexible plastic will push through where copper won't. I realise that I need a barrier pipe to stop air ingress, but there are a range of different types of plastic pipe available and I'm...

Hello, I'm about to replace electric storage heaters with a wet system and need to size the radiators. Storage heater ratings are 2.55Kw, 3.4Kw and 1.5Kw. It occurred to me that rather than just replacing them with radiators having the equivalent output (which seem quite large to me) I could...

Have just bought a ladder type towel radiator for the bathroom. It's designed to be plumbed in to a wet system and can also take an electric element for use when the heating is off. Don't have a wet system here, so just plan to use it with the element. It just occurred to me 'though, that I...

We have a big house on 3 floors and our pump is about 14 yrs old. Still going, but is a bit noisy at times and I sometimes wonder if it is getting the water around the house as fast as it used to. What's the expected life of these pumps? Do they loose power over time? Would it be wise to...

I want to install a pump to boost hot water flow. Have looked at shower pumps and they seem to involve a lot a flanges, gravity loops etc.... Is there a way that I could fit a pump to the cold water feed at the bottom of my HW cylinder and thereby boost the pressure of all the hot water...

I had a hot water cylinder specially made to fit in a tight space. Annoyingly I didn't specify the size of the outlet and they put in a half inch thread. This means that I don't get a high enough flow for a descent shower. I don't want to install a pump or go to the hassle of raising the...
