TRVs on all rads

[blackie2708]

Is it possible to fit trvs on all rads as i don't have one on the landing i can leave on all the time. if so how can i do this.

What boil;er & system? Depends on the details.

fitting therms on all rads. is now the recommended method from the powers that be. It is achieved by using an automatic bypass valve. However as chris says it all depends. If you have a solid fuel boiler for example it could be difficult to achieve safely.

My boiler is an alpha 24x combi.

Beg to differ, but you shouldn't have trv's on every rad. There should not be one where the roomstat is fitted.

let me guess new regs?

i am not a plumber but is it not true to say fit trv on all rads except one which will act as a by pass (that is what we have except bathroom which has no trv)

There can be no argument as to how it should be done. Part L of Building Regs 2002 (Energy Efficiency C&G) says TRV on all rads except where roomstat is to create 'boiler interlock' AND an auto bypass (which may be in the boiler, eg in combi).
