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 -

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

Existing houses present a much greater challenge than new ones in terms of energy saving. However in terms of reusing building materials they often provide better opportunities.

Larch house entrance
Although not self built, the two passivhauses at Ebbw Vale may be very relevant to many self builders. Built in 2010 as show houses mainly for the attention of housing associations, they are attractive and innovative while being relatively modest. The 3 bed Larch House is clad with a locally sourced [...]
straw board
Straw board is made from waste straw with usually about 2% MDI adhesive binder. In the past the reputation of straw board has suffered mainly due to people trying to skimp on the thickness, a bit like with hardboard. It can make for very economical internal surface linings with good thermal [...]

Green roofs
There are several possible ways of improving the ecological design of roofs:

The main types of walls
Regardless of the type of wall construction, all walls have certain functions to fulfil and certain challenges to contend with. From a green perspective, three of the most important aspects of walls are their insulation values, the embodied energythe total amount of energy it takes to make a material [...]

Good external doors are quite hard to source in the UK because we have had a poor tradition of insulating and draught proofing them. This is why eco-house builders often use the imported Scandinavian and German ones which are available here.

New buildings
As a building material, locally sourced (or possibly newly quarried), reclaimed stone may be a viable option but suffers from the drawback that stone itself has virtually no insulating value.
This can obviously be overcome by including sufficient insulation within the rest of the wall construction but it does tend to lead [...]
It is very cheap and easy to build in wall insulation at the beginning compared with the complicated job of adding more later. It is only a few decades ago that insulation was not bothered with at all (cavity[for the purposes of part B of the Approved Documents] - A space enclosed by elements of a building (including a suspended ceiling[for the purposes of part B of the Approved Documents] - A part of a building which encloses and is exposed overhead in a room, protected shaft or circulation space.
