I work for Vokera. I think it's 86% of what we sell are combination boilers so brining in the OT for system boilers wasn't a starter for us although we sell it abroad. DHW on a combi on our boilers has to be from the control, the selector is disabled on our combi boilers, not on all other...

I work for a boiler manufacturer that when tested the evohome did not work with smoothly as the boiler requires an instruction from Evo to adjust DHW temp which it couldn't do however I could answer some other of your questions. Yes, it sends and adjusts flow temp plus also return, DHW , and...

I work for Vokèra as a technical trainer so am partisan however since it and the slightly lower modulating Synergy boiler were launched about a year ago we have people asking to come and see them. Till September warranties are extended as part of a promotion, 12 years on the Pinnacle and 10 on...

He cut the collar because he forgot to put it on and couldn't be bothered the disassemble it I reckon.

If you are looking at a heat pump long term or sooner,with or without grant the Riello NXHM (R32) is tried and trusted or smaller, the Carrier AquaSnap (R290). If you want a hybrid and keep your boiler, no grant at the moment, then either will communicate with the Vokèra Pinnacle or Synergy...

They can but not always, so much depends on the boiler. I ran trials at home on my system and found around a 1% advantage in both together but comfort was smoother with WC alone on a simple timer switching from a comfort temperature to a setback temperature overnight or when we're both out. If...

The heat loss is quite low so you'll want a boiler that can modulate low to avoid as much cycling as possible. Check whether the boiler can be range rated (restrict its maximum heating output) and how low can it modulate that output too. Not all boilers can use WC and OpenTherm together...

I think you were looking at the 35kW Pinnacle, that's fine if you have the cold supply to use 35kW or like water hotter than necessary but otherwise choose a lower output, 25 or 30kW. Don't worry about heating output as you know they modulate lower than almost everything on the market. I'd also...

Oh, I work for them as well as being a fan but I just answer questions, don't try to convince.

Praise indeed, thank you.

All Vokera combi models

If the boiler is going in the same place the delay will nearly always be the same unless you use Smart preheat, not standard preheat. (smart preheat is available in the winter and uses heat when the boiler turns off from radiators to pre-warm the hot water. This is using heat you've already paid...

If your fan is working why do you need a new one? Why is the boiler one of the worst ones, did the engineer give a reason? It's a sod to service that's true but if it's working he possibly doesn't like the idea of actually stripping the boiler and servicing it. A fixed price repair from Vokera...

I missed the 8m of 15mm.

Before you can say ditch the combi keep the old pipe it would be useful to know the output of the proposed system or heat only boiler the combi would be ditched for. System and heat only tend to be higher outputs, 20kW's possibly and the pipe needs to be sized for the boiler input irrespective...
