    New boiler - Inhibitor top up?

    During an install of new boiler ('old' boiler died after 11-12 years) the system was "drained" but I guess maybe 90% of water was left in the (rather large) underfloor pipe system. What is the best way to tell how much inhibitor should be added in this case? (also taking account that system was...

    Thank you for this.

    Noise from 8-Bar filling valve (Megaflo)

    I remember (few years back) calling a local plumbing firm (well known) asking about a service to megaflo system and they told me over the phone that it doesn't need any service... I'll look around for this service. BTW what does this service checks include? which parts? how often do you do it...

    Noise from 8-Bar filling valve (Megaflo)

    In our sealed Megalo system, when hot water tap is used (say in bathroom shower) the megaflo is taking in some fresh water, I guess to compensate for the water used. The incoming water go via a pressure relief valve [most likely its this one: Heatrae Sadia 8 Bar Pressure Relief Valve -...

    New regular boiler (heat only) in a sealed system??

    Hi, I am replacing our 11 year old boiler (due to H.Ex. leak) with a new one. This is in a "sealed" system with red expansion vessel in airig cupboard & a megaflo (no tank in loft). However the exisiting boiler is Vaillant ecoTEC 4xx boiler - which is satated by vaillant as an "open vent" boiler...

    Fittings for drinking water

    Hi Have a little job under kitchen sink and need to know how to identify fittings (valve, tee, coupler) suitable for drinking water. Should I be looking for only EN-1254-1 or EN 1254-2 or something else? For example, is this one good for drinking water...

    Reverse Osmosis System- Which Tap?

    Hi, I am considering installing an Undersink RO System, space should not be an issue (I think). We currently have a Quooker (instant boiling water) cylinder and tap installed which we hardly use. I am planning to disconnect and remove the quooker tank from under the sink but the question is...

    No Hot Water When UFH Controller is On?

    UPDATE: I've now traced the source of this problem (no hot water) to the Honeywell 7 day Timer (ST9100C). After 8 years of service it started to fail intermittently. This becomes clear when there is no click sound when changing between the 'off' and the 'cont'. There some help videos online on...

    No Hot Water When UFH Controller is On?

    Well, the port itself was not replaced, only the motorised head for the valve (U4043H) which was buzzing after 7 or 8 years. It is definitely the correct part. I was thinking one possibility is that there may be an additional valve (internal in the megaflo) which is linked to the controls? Could...

    Biocide for underfloor heating?

    How essential is biocide in UFH? I have brown dirt in nearly all flow-meters and heard different views on how effective biocide (such as X700) may be. Some say brown colour is from iron particles (magnaclean is fitted) other say its from bacteria living in the pipes? On a close topic: Is it ever...

    No Hot Water When UFH Controller is On?

    Thanks, initially I thought along the same lines but the zone valve before the megaflo was recently replaced. I had an inkling it had to be a controller issue but I don’t yet understand how physically it is possible. Even when I took the head of the zone valve off and manually opened and closed...

    No Hot Water When UFH Controller is On?

    Hi, My CH system is made up of 3 or 4 radio controllers. Each controller is responsible for a manifold & pump with attached number of UFH zones and radio operated room thermostats. I just found out that the flow pipe into the hot water tank (megaflo) starts to cool down rapidly when one of the...

    UFH Water quality and possible valve leaks

    It seems like the consensus is that in UFH dirty water does not equal problems (leaks). So this time we’ll just replace the valve and see how long it lasts before going for any water renewal.

    UFH Water quality and possible valve leaks

    Yes, magnetite CAN be the cause, the question is can I confirm this is the case. Does brown, colour is like Redbush Tea :), in flowmeters mean presence of magnetite? If so do I need to flush the system? A MagnaClean Filter was fitted on the return pipe 3 years ago, and it does pick small tiny...
