Why You Should Buy a Mitsubishi Electric Air Source Heat Pump

E-Si as a heating solutions provider install Air Source, Ground Source and Water Source Heat Pumps.  Here is some reasons why you should invest in a Mitsubishi Eco-dan!  Air source heat pumps offer some great advantages over gas and oil heating systems.

Here are 10 reasons why you should consider buying the Mitsubishi Electric as a replacement or alternative to fossil fuel boilers.

1) Save Money on your Fuel Bills

When compared with mains gas the Mitsubishi Electric will save you up to 40% on your gas bills (when heating your home with the same amount of thermal energy)

2) Reduce your carbon emissions from your home’s heating by up to 50%

We’re all conscious of having to reduce our CO2 emissions and by installing a Mitsubishi Electric air source heat pump you will reduce your home’s heating emissions by up to 50%.

3) Leader in its Field

The Mitsubishi Electric inverter driven technology matches the heat demands required of it efficiently and economically.

4) Low Noise Levels

Stand next to Ecodan and be amazed at the very low levels of noise it creates, in this sense it really is a world leader.

5) Easy Installation

The installation is just as easy as a standard oil or gas boiler and you do not need expensive gas safe registered or refrigeration engineers.

6) Low capital cost of Installation

Payback of the small extra capital cost of the heat pump over fossil fuel boiler is relatively short giving significant savings on running costs.

7) Three different models to choose from

There are three different sizes of Ecodans meaning a solution is available from small flats to large 4-5 bed houses and beyond.

8) Low Maintenance and 3 year warranty

Low annual maintenance is another star feature of Mitsubishi Electric air source heat pump, being little more than a visual check of the external unit. Mitsubishi Electric also offer a 3 year warranty to give you peace of mind.

9) Renewable Heat incentive and MCS

Ice Energy and each heat pump model is accredited under the Microgeneration Certification Scheme (MCS) which will allow you to claim the Government’s proposed Renewable Heat Incentive (RHI).

10) Award Winning Design

The Mitsubushi Electric recently won the Environment Energy Product/Service category of The Environment and Energy Awards. The judges praised the product saying it was “A neat unit that could prove acceptable to the environmentally-savvy domestic user who want to do their bit to cut carbon emissions.”

Pauls Blog: The Isle of Sark running on Renewables?

Views from the beautiful Island of Sark where our R&D is based @ Clos Bourel.  Could this Island be entirely run on Renewable Energy?

I am in Sark at the moment and I’ve been working at our R&D site here and attending a Renewable Energy Talk. Everyone was very excited and excitable. However lots of talk but no real understanding.

I think the time is right to hit Sark with a grand proposal.

The Sark Electricity Company owner is basically saying oil is going up and will continue to do so and there is an urgency to move to Renewables. However there are a lot of misconceptions and misunderstanding. He has been using the University of Southampton to research a number of proposals he has which includes a tidal watermill. They have looked at PVs and wind but have been largely dismissive.

The way I see it Sark needs to:

  • Install a Sunny Island / Battery system.
  • Utilise their existing diesels sets as backup to the battery/island.
  • Encourage other ‘islands’ around the island at strategic points.
  • This would enable micro-scale grid connect by others
  • Change SEL policy to allow buy back (crucial). Electricity is about 40p a unit and islanders would love to be paid just something....however trials so far with Sunny Boys have not been very successful. I need to bring my laptop and measuring equipment over next time and have a serious go at monitoring the mains. So a duel issue: a) reliability of existing mains supply b) changing the way it all operates to allow others to add to the grid with PV and wind.
Up to that point that’s a good start. However Sark waters has some of the best tidal currents in the world, so it can’t be ruled out of the renewable energy mix. I have noted in the past the claim that the Proven wind turbines can be used as water turbines in rivers. It would follow through that they could be used as tidal turbines. My belief is that several small scale turbines would be very cost-effective, using tried and tested technology which could be serviced by local service industries:  there are experienced fisherman and divers used to working in deep waters and extreme weather conditions. 10 x 6kW Proven machines could generate 60kW peak. Combined with PVs, Micro-wind, batteries and Sunny Islands this would be hugely beneficial.
Because Sark has steep high cliffs the island is also suitable for pumped storage systems.
There are streams and so we cannot rule out ‘mill ponds’ and Pelton wheels.
If Sark gradually moved to low carbon, lower cost electricity and get off oil there would be a move to do three things: a) electrify the heating systems (using heat pumps) b) use more electricity (it always happens), for appliances and comfort needs c) electrify the transport system.
Heat pumps are interesting. We have huge experience in this area and whilst Air Source is the likely choice, Water source form sea water is also a good choice. There is plenty scope for traditional ground source (particularly boreholes into granite), but also there is plenty of water available under the island for water source via boreholes, but most people are close to the sea!

Mitsubishi Air Source Heat Pump which could be the likely choice to electrify the heating systems and move away from fossil fuels.

I think that’s about it. That covers my thoughts about Sark in a penultimate plan that has spanned 12 years of experience of working in the island.

Meanwhile we have the aim to complete the Clos Bourel Energy Project in Sark to a fairly conclusive milestone which has taken years of work to get to. Essentially it has been our base for R&D where it has all gone full circle, having started from Clos Bourel, worked out to current clientele and working back into Clos Bourel.

Eco-Homes and Eco-Developments

We are looking for partners to finance some eco-projects or an existing developer to co-develop truly advanced and real eco-houses (unlike some of those that purport to be so), from 50% Carbon Zero to 100% Carbon Zero to 120% Carbon Zero - what we call Carbon Zero+ Homes (homes that produce more energy than they use).

We want to partner in creating one-off homes, groups of 3 and up to 9 homes. We are not interested in low cost bottom end of market. We want to build high quality, technologically advanced, ecologically sound homes at differing levels of the market above low cost. The eco-builds could be new-build, conversions, renovations or apartments. They can appear on the outside and inside as normal as any other building or we can accentuate the eco-credentials by visual design.

We want our homes to be simple, aesthetic, easy to build or convert, high quality, with low running costs and easy to run, setting an example to builders, developers and architects on the island of Guernsey, Jersey, UK or France - and of course make a good profit.

We have an experienced team of expert Renewable Energy Engineers with core skills consisting of hydronics, electrical engineering, carpentry, and project management supported by our technical services department able to handle initial designs, the build itself, installations and post-build service and maintenance. We have access to architects and conveyancers who would work as members of the team internal to our organisation, keeping as much of the burdensome work within our directly managed framework. All of our staff are trained in eco-builds under our E-Si Academy umbrella.

We believe we can achieve a build only slightly more expensive than conventional builds, simply because our experience and understanding makes it possible to get every detail right first time, with everything integrated into the build from first design.
