On Friday I had my CH pump replaced, now the heating isn't working properly. The boiler fires up for a short period, there is a whooshing sound and it shuts down. The house doesn't get warm because the heating is only on for short bursts. I've bled the radiators (a few of which actually do get hot). The expansion tank looks normal and the valve opens/closes.
My plumber is away on holiday next week, any suggestions? Thanks
