I want to replace my ancient Rayburn 480D oil boiler/cooker. The boiler side is rated as 25.7kw. I am considering replacing it with a Grant Vortex Pro External Model. Does anyone have an opinion if I can get away with the 21-26Kw model or should I use the 26-35model. Am I right in asuming that the Grant ought to be way more efficient than the Rayburn.
Thanks in advance.
