Vokera had two, the first compact and the vokera option were both Bi thermal, and both suffered from premature heat exchanger problemsModels from Ferroli, Potterton and Worcester I have worked on, and now I hear that Vokera also had one.

In the 70/80s, the insulation value was appalling. Most homes have uprated their insulation greatly. Also rads were 10% oversized generally. These days with uprated insulation, a home can be run at 60C with no problems. A decent weather compensator will keep the flow temp down quite low most of the time.Even with double glazing the existing radiators may be too small to provide adequate heat when CH water temperature is reduced down to 60°C
When heating was installed the radiators would have been sized for 80°C water and double glazing in place.
Perhaps an upgrade to triple glazing is the solution to preventing hazardous hot slugs in the domestic hot water supply from certain makes of combi boilers.
Intergas heat exchangers are built like tanks.Vokera had two, the first compact and the vokera option were both Bi thermal, and both suffered from premature heat exchanger problems

Intergas heat exchangers are built like tanks.
Lol...as well as low gas bills.
To add...
The likes of Intergas have integrated weather compensation. Fit an outside temperature sensor and an Opentherm room temperature sensor, then low flow temperatures are near guaranteed - as well as low gas bills.
Just to add, I never said that the Intergas suffered the same problems, I merely stated that a few older bi-thermal heat exchangers suffered from problems, I didnt mean that I have ever seen the Intergas suffer from itIntergas heat exchangers are built like tanks.
That is such a vague statement as to be meaningless.Very few homes have not updated their thermal insulation.
Many do. The two sensors, when the system is up to, or near setpoint temperatures will have the flow temperatures markedly reduced.Don't do that it won't work
I see reading comprehension is not your strong point.That is such a vague statement as to be meaningless.
Intergas have a clever pre-heat function. In the heating season the heat exchanger is constantly pre-heated.
Writing vague statements meaning nothing,is defo yours.I see reading comprehension is not your strong point.
