How can I make my central heating quieter? Recently had to drain it down a couple of times, and now everytime I have the hot water or heating running, theres a loud whooshing and gurgling sound, like water is trapped in the system and being circulated.
The system comprises a system boiler at front of house in bedroom cupboard, cylinder in back bedroom - linked via pipes through loft. The pump and 3 way valve is adjacent to the cylinder. From the cylinder cupboard, the central heating pipes go down and horizontally under the floor. Above the cylinder is the header cistern.
How can I stop this noise?
And would a maintenance agreement with e.on cover 3 way valves? The rads near the cylinder get hot when the hot water is on. Or could this be causing the gurgling? All the rads have been bled.
The system is 20+ years old, when I next drain it down should I throw some inhibitor in the cistern while its filling?
