Iím new here. Iíve recently bought a house in Scotland as a holiday home. At the present heating and hot water run of two back-boilers which ar heated by open fires. (In two separate rooms) There is a twin coil hot water tank in the drying room with gravit circulation. (I believe) The central heating (9 radiators) is circulated by one pump. Both bac boilers feed the central heating. Can someone make an educated guess at how the water flow through th radiator has been designed? Will it be kind of one circle with the water being pumped around an around? If I remember rightly, the Radiator can be adjusted separately, s there must be some form of a bypass or something.
Sorry I canít give more precise information, but I live in Germany, an canít investigate into the system myself at the moment.
In May, I want to include a combination boiler into the system. Eithe gas or oil, I havenít decided on that point yet (no mains gas). How do I best go about it?
I believe that I can get rid of the hot water tank under the roof since Water will come directly from the new combi-boiler Is it Ok to blank the gravity feed and return pipes from the boiler i the attic, or do I need to open the fireplace and blank the ends at th boiler? Or should I just short-circuit the pipes in the attic?
I would very much like to keep the back-boilers operational for heatin purposes. Is that possible? I assume that the heating will be run of the combi-boiler a lot of th time. But when I light a fire I would like to have the feeling that Ií not wasting a lot of energy. So if it is possible I would like to hav the back-boilers included into the system. When the combi-boiler is heating the house, depending on the way th central heating piping has been designed; the back-boilers would act a a radiator warming the air in the fireplace and causing a drought up th chimney. ??? Would it be feasible to install a "Bypass" ?? Iím thinking of a 3 - way valve which sits in front of the water flo to the back-boiler. In one position the water flows through the back-boiler and gets heate by the fire In the other position the water flows through the bypass and doesní heat the back-boiler unnecessarily.
Or am I construction a Bomb?
Iíd be very pleased for any kind of feedback. regards Erec
