The advantages of spray foam insulation. Icynene is a form of spray foam insulation. The thermal conductivity of the insulation is about the same as mineral wool. It has the advantage of making the building very air tight. Because of
What are the pros and cons of Sheep’s wool insulation? Sheep’s wool insulation is made into rolls and slabs very similar to those made from fibreglass and mineral wool insulation. Rolls of insulation are generally used above flat ceilings
CHP stands for Combined Heat and Power. A CHP unit is a heating system fitted with an electrical generator so that it can provide heat and generate electricity at the same time. You might be forgiven for asking why anyone
Passivhaus is a German word for passive house. The literal meaning of the word is a house that is unheated. Imagine having so much insulation in your house and such good triple glazing that heating was completely unnecessary. The sun
When you take a bath the waste water goes down the plug hole. Obviously this waste water is quite warm. Waste water heat recovery means recapturing the heat from this water. A copper pipe is coiled around the pipe that
The idea of the Green Deal was that people would borrow money from their gas or electricity companies to insulate their house and replace their old central heating system and windows. This money would be paid back over 25 years
One of the major sources of heat loss is through windows and doors. A typical window or door has a U value of 1.60 (a good quality modern type) and that’s 5 times as much heat loss as a wall
Vacuum insulation works in the same way as a thermos flask. The thermos flask uses a vacuum between two glass walls in order to prevent heat travelling by conduction and silver on the walls to reflect radiant heat travelling as
Buildings that are off the gas grid still have to conform to the same environmental standards as buildings anywhere else. This is a problem because the standards required by Part L 2013 are very strict and the efficiency of fuels
Natural gas contains a large amount of hydrogen. When hydrogen burns it becomes water. In a hot gas boiler when the hydrogen burns it will change into steam. In a condensing boiler this steam is made to condense on a
