I cant find the model number 632, you have 2 so does one heat hot water and other heating? Or do they just work in Tandem. If they work in Tandem check that your Zone valves are working. This is a most Likely cause for hot water but no heating.There should be a manual slide on it or them that you will feel move when you switch to heating. If the boilers work independently are both boilers firing?

Apologies they are 630 models and neither ignite properly, they try to fire then give up!
