Question on upgrading hot water cylinder

Cascade it ideal Evomax was my go to set up when commercial . Regards kop

It is not broken, and likely I will not change it this year. My main motivation with replacing it is to further cut our yearly gas bills. Thus, if a modern and better insulated cylinder would make a difference, then I would certainly consider it.

Thanks. FYI, Manchester Calorifiers has closed down. It seems that McDonald Engineers do cylinders as well.

Thanks. I researched this quite extensively, and I also came across that article and it is rather informative. Currently, hot water and heating have different boilers. The hot water system is not as old or dirty as the heating system, because the hot water passes only through the pipes and cylinder coil. Thus, the coil acts as heat exchange itself. If we were to cascade the boilers, woudl it make sense to put a separate heat exchanger just for the legacy heatign system? Thus, the 2 boilers woudl provide hot water to (1) hot water cylinder through coile acting as heat exchanger, and (2) radiators through a new separate heat exchanger? If yes, with this set up can you regulate different temperature goign to (1) and (2)? Hot water shoudl ideally be at a certain tempearature for helath reasons, whereas heatign is more flexible.

This sort of project needs a heating consultant to advise and design a system suitable for the building i have fitted many plantrooms and boiler houses in my time and a properly designed packaged system will pay for its self over the next 20 years , so my advice research all you like but get it designed properly . There are many ways to do it my only consern would be water quality plate heat exchangers dont like a dirty system so keeping the system clean is vital, attached below is just a few worth considering.

Thanks for the feedback. The research I do is just for own better understanding, and certainly not for me to design a system I am not qualified to design. Are you John in the contact form for Lok?

No mate just a example they are the sort of outfit you should be approching though . Regards kop
