Introduction This document is the response from Rob Veck, GreenHomeDiary.com, professional Project Manager, and a Superhome owner that has achieved an 80% reduction on household emissions to meet the Kyoto target. This could not have been achieved without the installation of PV and Solar Hot water. A copy of this document has been sent to [...]

Calculations The concern about the heat pump is the running costs. Even though the efficiency is 1 to 4 (1kWh in gives 4kWh out), the economics & CO2 savings are somewhat different. My last bill including VAT 1 unit of electricity = 14.58p 1 unity of Gas = 5.17p (see note about split costs below) [...]
Segen provide a calculator at this link and there is a Romsey based company Solar Technologies that need further investigation. This post will be updated with further info as and when I produce a more detailed plan.
Do the energy companies prohibit the inclusion of battery backup (in the event of gid failure) for safety reasons ?
The requirement is to install a Solar Hot Water system capable of providing domestic hot water for a 300 litre tank. The existing tank is a Ultra Steel manufactured by RCM Group. It is a non-vented system and already has a secondary coil. The Visseman 200 gas central heating is currently plumbed into this secondary [...]
Given the current plans what additional insulation is required to reduce the amount of heat that is generated by the heat pump ? Assuming additional insulation is applied, how much electricity will be used to power the heat pump ? This information is an input to the PV requirement Is it possible that heat from [...]
The recent government Heat and Energy Saving Strategy discussed the “Whole House” approach (Chapter 1 Box 1.3) to considering a households energy needs and CO2 impacts as a whole. GreenHomeDiary is pioneering this approach – the different renewable technologies and energy saving considerations should form an integrated solution. The possible difficulty is that different suppliers [...]
There will be a combination of renewable technologies that will form an overal solution to the goal of achieving a zero energy usage for the house, which will also contribute towards reducing our carbon footprint. There is a minimum configuration of appliance that need to be operational in the event of a power cut :- [...]
