Domestic hot water

Traditionally, domestic hot water has simply been a choice between a combi boiler or a vented system (with the odd Point of Use water heater thrown in).

With water saving design, and zero carbon housing which will possibly become the standard in 2016, this all changes slightly for several reasons -

Emitters (rads etc.)

Central heating

Emitters tend to be of two types – traditional radiators and underfloor heating. It’s a bit of a toss-up as to which is better. They have their respective advantages and drawbacks.

Underfloor

a pleasanter heat because it is better distributed no wall space taken up by radiators possibly more efficient because of lower [...]

Flues

Fluespipe to conduct gas, typically ventilation air or boiler exhaust. see more on Flues are pipes or ducts which carry waste gasses away from a building to the air outside. This can be caused by two possible mechanisms

the exhaust gasses are hot and rise naturally up the fluepipe to conduct gas, typically ventilation air [...]

Service Ducts

June ’12

The close grouping of services and the placing of them in a fairly centrally situated service duct, usually a duct which extends vertically through the house, has a great deal to recommend it but is seldom executed well.

The forerunner of this (still to be found in some older houses) was the [...]

Alterations & Fashion

‘Energy use’ is usually associated with how much energy is used to construct a new building. However, this is only part of the story. Most buildings get altered and repaired and redecorated a considerable number of times during their lifetime and taken to an extreme, some houses are constantly having ‘makeovers’. This can vastly [...]

Home Automation

There are many possible uses of home automation which can enhance the green rating of a house but probably the most obvious and least used is the ability to turn off heating for periods when the house is not occupied and then turn it on remotely before returning.

Telecoms

While it takes a crystal ball to know how telecoms is going to evolve over the next decades there is a strong likelihood that the ability to easily rewire large parts of a house will be a major advantage. Although wifi has certain temporary advantages, the benefits of optic fibres connecting directly with computers [...]
