warm
A warm front is a density discontinuity located at the leading edge of a homogeneous warm air mass, and is typically located on the equator-facing edge of an isotherm gradient. Warm fronts lie within broader troughs of low pressure than cold fronts, and move more slowly than the cold fronts which usually follow because cold air is denser and less easy to remove from the Earth's surface. This also forces temperature differences across warm fronts to be broader in scale.
Clouds ahead of the warm front are mostly stratiform, and rainfall defiantly increases as the front approaches. Fog can also occur preceding a warm frontal passage. Clearing and warming is usually rapid after frontal passage. If the warm air mass is unstable, thunderstorms may be embedded among the stratiform clouds ahead of the front, and after frontal passage thundershowers may continue. On weather maps, the surface location of a warm front is marked with a red line of semicircles pointing in the direction of travel.
I have two large column radiators in my kitchen diner. For the last couple of winters they have taken an age to heat up properly and the boiler has to be turned to max to get them to get to this stage. They are big units, 4 coulumns and I understand they take a lot of water.
I have bled them...

Hi All
I was wondering if I'm barking up the wrong tree here?
I've got a new build project underway and need to consider how to heat the place. The house is in a rural location and town gas is not available and I'm not keen on bottled gas either. The main sources of fuel readily available...

OK folks,
I am really struggling with this one and it would seem my plumber is as well, so here goes the catalogue of events to date:
1. Back in the summer I upgraded my ancient boiler to a modern worcester greenstar, no obvious problems at the time as I was only running the hot water. At that...
