heats
Latent heat (also known as latent energy or heat of transformation) is energy released or absorbed, by a body or a thermodynamic system, during a constant-temperature process — usually a first-order phase transition.
Latent heat can be understood as energy in hidden form which is supplied or extracted to change the state of a substance without changing its temperature. Examples are latent heat of fusion and latent heat of vaporization involved in phase changes, i.e. a substance condensing or vaporizing at a specified temperature and pressure.The term was introduced around 1762 by British chemist Joseph Black. It is derived from the Latin latere (to lie hidden). Black used the term in the context of calorimetry where a heat transfer caused a volume change in a body while its temperature was constant.
In contrast to latent heat, sensible heat is energy transferred as heat, with a resultant temperature change in a body.
So.. we have a 20 year old (approx) Netaheat Potterton that comes on everyday and seems to be working okay.. the radiators get hot etc... BUT it isn't heating the hot water from the hot water taps (anywhere in the 2 bed house).
We do have an immersion heater that plugs in to I think the same...

I have a vokera boiler with a drayton mid way valve to choose either h/w or c/h or both. When valve is set to c/h everything works fine but when valve is set to h/w the vokera boiler cuts out after running for approx 3 minutes.
Is the coil blocked or has it got an air lock?
I had a plumber fit...

Hi all,
I'm a complete novice when it comes to plumbing & central heating systems so please bear with me... ;)
We have a Glow Worm Flexicom 15hx boiler (located in the kitchen) which was installed just under four years ago. During the time we've had the boiler we've had a number of occasions...
just a quick note changed around 5 of these recently on various microgenus boilers 23,27,31 se and 32 he mffi the upward arrow stickers are coming upside down if they dont fit turn them upside down:D you dont have the wrong part you have a retard in the alto heat exchanger factory obvious fault...
I have a sealed room boiler and in summer I use it to heat water. There is a switch on the boiler which I have in the "summer" position. But when the boiler is set only to heat water, a couple of rads get very warm and others slightly warm, Do you think it would be ok, in the summer, to turn...
