Grand Designs

December 2021

Grand Designs magazine is essential reading for anyone who is building, renovating, or improving their own home. In each issue you can expect to find 40+ pages of inspirational real homes complete with in-depth project details and exclusive tours of new TV houses. Up-to-date information allows you to stay abreast of the latest architecture, design and construction ideas and innovations. Practical project features include advice from industry experts on a wide range of challenges such as building on an awkward plot, overcoming a lack of light or space, or working with a tight budget. And, as designing a kitchen or bathroom is one of the most complex – and expensive – room transformations to tackle, every month you’ll find a project feature on each, along with beautiful real-life case studies.

tips for success

AIR-SOURCE HEAT PUMPS TIPS FOR SUCCESS Retrofit tips by David Hilton from Heat & Energy ( • Radiators will need an increased surface area to be compatible with the low flow temperatures of an ASHP. Effectively, you are changing the emitters from a radiant heat to a convective heat (turn to page 18 for a selection of suitable designs). UFH is particularly effective when used alongside a heat pump. Be sure to design it to have close pipe centres (no further than 150mm apart). You’ll also need to install good insulation under the pipes to avoid conductive heat loss. • An existing hot water cylinder will need to be changed for one that has a bigger, heat pump-compatible coil, plus a larger storage capacity. Hot water is stored at a…

temperature control

BUYER’S GUIDE RADIATORS Temperature control Pairing your heat pump with the right radiators makes all the difference to a room and your heating bills Feature ANDREA MANLEY Whether you’re updating a heating system or adding a new one to a self-build or extension, there’s an array of radiators in increasingly inventive styles, colour and materials. Getting the right heat output for the space is vital. Radiators come with a BTU rating, which gives heat output calculated in British Thermal Units, so once you know how much heat the room needs you can choose the right size and style to suit. Aluminium models heat quickly, but they also lose heat rapidly once switched off. Low-surface-temperature radiators and low-water-content radiators are efficient, using the minimum amount of energy to heat the space and…

warmed by the earth

GROUND-SOURCE HEAT PUMPS Warmed by the earth How to harness the plentiful thermal energy beneath our feet Feature REBECCA FOSTER Two metres below ground, the soil maintains a fairly consistent temperature of around 10ºC and is unaffected by cold weather. Powered by electricity, a ground-source heat pump (GSHP) extracts warmth from the earth using collecting pipes buried below the surface. A setup with pipework laid in trenches at a depth of around 1m is the most common option, but if there is a lack of sufficient space on the plot, a vertical borehole can be dug instead. A solution of water and antifreeze flows through the pipes, picking up warmth as it moves. This liquid is channelled to a heat pump unit, most often kept inside the house, where it is…

breathe easy

MECHANICAL VENTILATION WITH HEAT RECOVERY Breathe easy The lowdown on a system that circulates warm, filtered air around the home Feature REBECCA FOSTER Mechanical ventilation with heat recovery (MVHR) draws stale air out of each room at an extraction point. The air is passed through ducting to a heat exchanger and expelled outside. The extracted warmth is transferred via the exchanger to fresh air flowing through a separate run of ducting into the rooms. Filters in the main unit remove particles so that the circulating air is free from pollutants. Usually installed in a loft, basement or plant room, the air-handling unit is the hub of the system. It is connected to a series of ducts that are attached to extraction and supply points. Provide the best setting MVHR is most…

focus on woodburners

BUYER’S GUIDE STOVES Focus on woodburners Opt for a design that makes maximum use of its fuel to ensure an energy-efficient and eco-friendly stove Feature ANDREA MANLEY Whether you’re after a contemporary design for an open-plan space or a traditional model for a cosy living room, woodburners have eco credentials that open fires can’t match. From January 2022, all new woodburning and multifuel stoves must meet Ecodesign legislation, requiring stoves to run at an efficiency of at least 75 per cent and to have smoke emissions of less than 40mg/m3. Look for the SIA Ecodesign Ready label when buying – all models shown here are Ecodesign ready. If you live in a smoke-control area, you’ll require a model that offers a smokeless burn and is DEFRA approved. MODERN STATEMENT Contura’s i8…

sustainable approach

ECO HEATING GUIDE Sustainable approach Enjoy the perfect indoor temperature and reduce your home’s energy use Feature CAROLINE RODRIGUES We are facing a challenge. Climate change demands that we adapt many of our habits to live more sustainably, while at the same time the financial and environmental costs of heating our homes increases every year. The government’s response is the proposed Future Homes Standard, to be introduced by 2025, which will require new-build homes to be futureproofed with low-carbon heating and improved levels of energy efficiency. Meanwhile, there is plenty that we can do now to cut back or even eliminate our home’s reliance on fossil fuels. Self-build solutions When building a new home, all the energy-saving elements must be considered and balanced from the beginning of the project. The gold…
