My daughter and family have moved in to a chalet bungalow and one upstairs bedroom lacks a radiator.
My son in law wants help adding the rad. He can't find a header tank only the main tank in the loft so assumes itâ€™s a sealed system.........They have a hot water tank in the airing cupboard if that makes a difference to the type of system.
I know we can close all rad valves and just drain the pipes but I fear that some of the valves might not shut the water in the rads off [not temp controled type valves].
1. If a sealed system where would the top up bottle be located, and do we turn off the mains feed in to the property/ or the bottle stop valve if fitted, to stop the bottle/boiler being topped up when draining starts?
2. Are push fit joints suitable for central heating?
3. Whatâ€™s the knack in getting the Tee joints in the flow pipes if they don't move enough?
4. As the addition is upstairs do we need to drain the whole system?
