Hi everyone I need some advice on the Vokera easi heat plus 25c and the DHW temp switch. There is a knob for DHW but it doesn't have any numbers on it for example 1 to 10 but has ten dots each going from low temp which is dot 1 to full temp which is dot 10, it is a bit annoying as I don't know...
Hi everyone, I have a question about domestic hot water via a combi boiler and how it differs in temperature in the kitchen and bathroom. (The DHW temp gauge on the combi boiler is in the middle-all incoming water into the flat is mains fed)
In the kitchen when I turn the mixer tap all the way...
Hi,
I am having an issue with a Viessmann Vitodens 200 installed for a client.
The boiler is a B2HA 60kW commercial with Combustion controller lockout fault E3.
It is weather compensated, system Type 4 the mixer is a 1 1/4” Divicon
I have spoken to Viessmann who suggested the Divicon was...
Hi All,
We live a house heated with "viessmann vitodens 200" running on gas.
Hope you will excuse my question, but we have a doubt if it's safe to run the heating only on summer mode so called "DHW".
We are recently move to a house with a mentioned gas boiler, and previous owners told us to...
Hi
Anyone help and advise on the best option for a DHW secondary circulation (SC) layout.
Scenario 1
I need to install SC in a large new build. The unvented cylinder will be in the middle of the house and so I would like to have two SC ‘loops’ i.e. T off the hot from the cylinder and go to...
Have a query regarding a morco combi boiler in a mobile home. It's set up with a link on the thermostat connections within the control panel and heat is controlled by Trv's. I'm planning on adding a hive thermostat to give me more control and intend to use the app. My question is, when the DHW...
Hi guys. New here.
Basically I bought this house 2 yrs ago. Back when I bought it I took over an existing plan with British gas for my boiler servicing.
Upon first service, I asked about hot water as if you turned the bath tap on more than 1/4 turn it ran like warm at best.
He said he...
Hi there, bit of a hot water issue (or more lack of it) ever since I installed a new bathroom a few months ago. When the hot water tap is fully open the boiler heats the water as normal but intermittently the gas cuts out for 10-15 secs until the water cools back to 60 degs and then fires up...
Boiler has been fine for 8 months then the dhw started getting colder. Replaced the heat exchanger and the flow turbine and all good for three weeks and now cold dhw flowing cold again. Replaced the turbine again and the divert valve and motor and no difference. I have removed the divert motor...
Hi Guys, called out to a Biasi M90 with no DHW or CH. ignition pcb was faulty but since realised that there is no live to that board. I have a live feed into the main board and fuse is good. Do we reckon it’s the main pcb that’s at fault?
80e works 90 per cent well. But when running shower, intermittently stops heating and restarts.
It's not the DHW temp sensor.
I don't think the flow switch is tripping when demand is low (i.e as the water gets hotter)
I don't think the dhw O/H thermostat is tripping.
Other observations - CH temp...
Hi I have a boiler to service - ideal logic plus combi 30kw. Customer says when heating has been on for a while and they he runs the hot water the water is scalding hot.
Anyone have a any ideas? I was thinking maybe thermister on flow?
Would any of you knowledgeable chaps have any info on the Combi superflow by canetis, ever fitted any, know anything about them etc, I'm wondering if they could be a way to get a better shower in my place with a WB 24i ?
i cant work out if they 'work", are miracle, a duff, or if i'd still be...
Hi there,
Boiler question, but nothing that contravenes gas regs.
To get to the point, the Vaillant EcoTEC Plus seems to have two knobs. One has a tap symbol, the other has a radiator symbol. Even the system boiler version of this boiler has two knobs.
What I cannot make out is what purpose...
Hello All-
(Usual caveats apply: I am the rather unusual part-time variety of a GSRE, training self-funded and slowly trying to make my way and gain experience- mainly do inspections and safety checks etc, have been on the Baxi fault-finding course relatively recently, don't profess to know it...
Since replacing the expansion vessel on our Viessman 333 gas boiler, we've experienced a major problem. When we want hot water only,(DHW) setting, the radiators are being activated! Obvious solution may be with the 3 way port, but the complete heating system is now automatically switching itself...
Evening all, I have a WB greenstar heatslave 18/25 external oil boiler. A few weeks ago the DHW started to get overly hot out of our taps, almost to the point of scalding. I checked the thermostat hadn't been turned up for any reason but it appeared fine. I turned it down though wondering...
I don't want to have just electric heated water, when using a lot it makes sense to take it from the 30 gallon hot water tank, however in the kitchen the amount of water I need to run is silly, so I looked at an under sink heater with idea of feeding it with hot water so I can select if heated...
I am moving house and looking to install a thermal store in the new place. I was thinking of an unvented store around 300l, with a single corrugated stainless coil for DHW.
Any suggestions on make/model/supplier?
Any ideas if I might be missing something? Worcester Greenstar 28i junior, hot water runs for 5 to 10mins then boiler flame cuts out and it over heats. I can hear the main heat exchanger kettling and banging for a few mins, boiler tries to fire 3 or 4 times, then it fires up and hot water runs...
