Well what an adventure it is to pick a new heating system in Sweden. It is a whole new world for me… I guess when you live in a polar climate it is pretty important but in many cases some of it does feel a little like overkill, but I guess the Swedes know just a wee bit more about heating than this Aussie!
Before even buying the house, the agent told us that changing the heating (värmepump) was the first thing to be done, which was kind of obvious when you saw the old system. It was oil heating (oljepanna), which consisted of two parts. The ‘panna’ which I guess is a furnace in English, basically the big mean green machine, (shown below). There was also the MASSIVE oil tank. Besides being downright scary looking, this is an incredibly inefficient way to heat your home in 2013, so changing was the only option for us.

Speaking of options… the world of options for heating systems (värmepump) was just utterly confusing. Basically we were tossing up between two options bergvärme (geo-thermal) and luft-vatten värmepump (which I have no idea what it is called in English, air-water heating pump is the direct translation). Anyway, the bergvärme is a really efficient way of heating your home and many will argue that it is the most efficient, this was my preference when going in to this as I had heard everywhere that it is the best option. The more we looked in to it, we found that the difference really was marginal. The cost of the bergvärme was significantly more, and the yearly running costs were marginally less. The calculation is around 20 years that you will break-even.
Aside from cost, to install a bergvärme just seems like a lot of work to me. And also the costs can increase if they need to drill more than they realise, which they don’t know until they start. Also they need to choose the right place to drill a whopping hole in your garden and our block of land is hardly ideal for getting a machine which weighs a few tonnes up around the back of the house. It felt like it would be almost impossible.
So in the end, with much advice from Energipojkarna we decided to spend our 96,000 SEK (around AUD16,000) on a luft-vatten pump. Not in this price was new elements (not essential), but included was the cost of removing all of the old equipment and an additional large water tank so I can enjoy my looooong showers. This is interesting to consider doing at installation, although it may add around 6000SEK, if you decide to do it later it will be around 20,000SEK and the installation will be different and it will use more electricity (so I am told).
The installation started with the removal of the old system and oil tank, then we had a delayed arrival of our värmepump and delivery couriers who left it sitting on the side of the road, literally, 50,000SEK worth of equipment which weighed around 300kgs combined, just left on the side of the road. Arrrgh… don’t even get me started. But then the guys from NR Kyl came, helped us get all of the stuff up to the house and began the installation.
I have to say, the guys from NR Kyl have been amazing. Incredibly efficient, helpful, quick, friendly and have in 2 days finished the installation, which is more than I would have expected on these beautiful Summer Days in Sweden! They have been great from the beginning and we have been really happy with the service and results. And here, where the scary old oljepanna sat, is a fresh, new and efficient heating system!!
To finish the job we decided to replace the existing delightful yellow elements with new elements (which are also not cheap), so NR Kyl will be back on Monday to do this for us. We are only changing the elements upstairs at this stage as we wont renovate downstairs just yet, and in the future we will have floor heating downstairs. Which I also wanted upstairs but apparently was not a good option, so I lost on that one! 🙂 You win some, you lose some!
