Google NEST 3rd-Gen Room Thermostat

The Nest smart thermostat by Google is the most popular on the UK market. It can replace a standard domestic thermostat and be controlled by an app on a digital advice (smartphone, tablet, laptop or computer). Its smart auto-learning features monitor how you use your heating and sync it with your behaviour. It can also form a personalised schedule for your home depending on ideal room temperatures, the insulation in your home and the current weather.

Home-owner benefits

  • Proven energy savings
  • It turns itself down when you’re out
  • Control it from anywhere.
  • Metal, polished finish
  • Install it on the wall or use the Nest Stand (sold separately)
  • High-res colour display
  • Farsight – shows you the time, temperature or weather

HIVE Smart Thermostat

The Hive Active Heating (smart thermostat) from British Gas is another familiar name in the market. Also able to replace a standard household thermostat, it offers another brilliant way to regulate your home’s heating parallel to your daily schedule. Just like Nest, it can be controlled on your digital device via the Hive app.

Home-owner benefits

  • Control from anywhere using Hive app
  • The app gives you control of every aspect of your heating. Turn it up, down, on or off, set schedules and get notifications if you accidentally leave it on when you head out
  • Boost your heating with a tap. If your home isn’t as warm as you want, boost your heating or hot water so you get cosy quickly. You don’t have to worry about turning it off – it does that automatically
  • Wireless, but can be mounted on a stand
  • Location detection will send you a reminder to turn the heating off when you’re out
  • Frost protection activates when the temp drops below 7ºC to prevent pipes from freezing

TADO Smart Thermostat

Control tado° from anywhere using the tado° app on your smartphone. Set personal schedules and receive reports and tips on how you can heat more efficiently to save energy. Get all the information regarding your heating and how much energy you are saving at a glance. You can also find tips on how to easily improve your indoor temperature.

Home-owner benefits

  • Control from anywhere using the tado° app
  • Uses your location to determine when to turn down your heating while you’re away from home, and then turn it back up again as you return
  • Wireless or wired options
  • With the tado° app, you can individually control the temperature in each room, so you’ll save as much energy as possible. Or you can set a schedule that works for you. (this feature requires tado° controlled wireless radiator valve heads installed in rooms controlled by the app)

ElectroScale2®

ElectroScale2 has been designed to prevent limescale build up in homes and commercial properties. If limescale enters the Heat Interface Unit (HIU) it reduces energy efficiency and eventually causes the HIU to fail. With an electrolytic scale reducer, limescale is reduced, protecting the HIU and enabling it to run more efficiently.

Where mains water hardness levels go beyond 200 ppm, Part L of the Building Regulations states that provision must be made to treat the feed water to water heaters and the hot water circuit of combination boilers to reduce the rate of limescale accumulation and the subsequent decline in energy efficiency.

Home-owner benefits

  • Maintenance free
  • Immediate long-term protection for the whole system
  • No running costs and no mains power supply required
  • Maintenance free
  • Part L Building Regulation compliant
  • Approved by WRAS (Water Regulations Approval Scheme)
  • 10-year warranty
  • KIWA approved

MagnaClean Micro2

Compact in design, the MagnaClean Micro2 is a double-action filter that targets the removal of magnetite in smaller central heating systems.

Home-owner benefits

  • 6% annual saving on heating bills
  • Immediate ongoing system protection
  • Extended system life
  • Reduced carbon emissions

MagnaClean TwinTech

MagnaClean TwinTech is a powerful dual-action filter that captures magnetic and non-magnetic debris as well as biological films. Specifically designed for use with underfloor heating systems.

Having had an estimate from another company who demanded total payment up front by bank transfer, I decide to look at other options for HIU repair. I contacted about 5 companies. Add Detail got back to me very quickly with a much better price and only wanted the cost of parts up front which I could easily pay by credit card. Jason the engineer arrived at the agreed time (he was early in fact) and did an excellent job, making sure that the system was working properly. He was very polite and made no mess. I have recommended this company to others on my development as there are always people having problems with the HIU's.

Fantastic service provided by Add Detail! After two terrible experiences with other companies, I discovered Add Detail through a Google search. I messaged them on WhatsApp and received a prompt reply. A few days later, Justin came over and delivered impeccable service. Despite being initially informed that I needed a full HIU replacement, Justin skillfully replaced the malfunctioning pump, leaving everything fully operational! He was incredibly nice and helpful. I plan to rely on Add Detail for all my future HIU servicing needs. I highly recommend them.
