Just looking to see people's opinions on linking 2 system boilers.
To keep it short an sweet, the existing system has about 28 very large rads, in an old building used as a children's nursery. Its had a 40 kw heat only boiler running it but it's not coped very well. The hot water is heated by immersion heaters.
They want the hot water heated by the boilers now.
My idea is to cascade 2 x 32kw ideal vogue system boilers through a 80kw plate heat exchanger that connects onto the vented heating side but take the cylinder flow and return from the sealed side using motorised valves.
Ill add a drawing in the morning.
- 2 domestic boilers to keep any commercial side of things out the way. U16 meter 2 meters away with no other gas appliances.
Im just wandering if anyone has done this.
Iv tried to talk to vaillant but they can be so hard work and I'm not a big fan of Worcester but I know they have this set up available.
