Ämne: Brittiskt NIBE 360P

Ledsen för dålig översättning, jag använder Google Translate.
 
Jag är nyfiken på att veta om någon av er är medvetna om de problem som alla har i vårt land?
 
Den 360P var mycket populär på en punkt med prisvärda bostäder utvecklare, tills invånarna betalade många £ 1000 för uppvärmningskostnader. Utvecklare var att installera dessa system utan någon annan värmekälla, och vintermånaderna berodde mycket på att nedsänkning. 100s 360Ps har ersatts med olika värmepumpar eller gas.
 
Jag undrade om du hade åsikter om detta?
 
Dålig design med NIBE värmepumpar ett stort problem i Sverige?

Hi!
There is a thread about this in the forum:
http://www.varmepumpsforum.com/vpforum/index.php?topic=52273.msg536342#msg536342

The information we like to know is the prize on gas (that you use for house heating) compered to electricity in UK?

The Nibe 360 isn't really a bad heating pump, but you have to be awere that is designed to heat up houses with good isolation, and what we know the houses in UK isn't isolated that much?
I wouldn't recommend a Nibe 360 to a house in UK unless it is really good isolated.

Unfortunately, I seemed to have missed out this piece of news, concerning NIBE forced air ventilation heat pump and U.K.  Agreed that houses in U.K. are not as well insulated as houses in Sweden, never the less NIBE 360 is a pretty lousy heat pump with a poor heat capacity (just 2KWH). We know all that from the Swedish experience and it would now not be acceptable in newer Swedish houses of present and future. People here who have had this system installed many years ago are now forced to have an additional source of heat to reduce electricity cost, for example wood burning stove or, air -air heat pump which are incidently more efficient and have higher capacity. I have a IVT 490/ Autoterm 190F (similar to the NIBE 360 and just as bad!) and realising how in effective it was, I was forced to install in addition another heat pump with a better economy and higher power (Toshiba air-air heat pump) to reduce my heating costs. If NIBE really presented a positive economic calculations to support their heat pump in UK (as this programme suggests), then they have mislead the housing estate and the tenants. We know how overtly optimistic energy saving calculations are made for these pumps by our installators here in Sweden too! UK has had gas driven heaters traditionally and since gas is cheaper than electricity, it is going to be a tough job trying to beat gas, even with the heat pump of fantastic specifications! Don't just blame the Brits' poor housing insulation for our heat pump's poor performance! The poor insulation actually exposed how poor the pump really is!

The standard calculation for a Nibe 360 is that it can probably save about half the gross heat energy for a good isolated standard house.
When i checked (google) price for gas/electricity i get about 5/13 pence/kWh, is that right?
In that case it is pretty stupid to heat up a house with a Nibe 360 since electricity cost 2,6 times more than gas?

My opinion is that people must be able to calculate themself.
Salesmen very rarely consider the economy for any else then themself.

The new building regulations for green houses in the UK are very simular to the once used as standard for new houses in Sweden.
The reason they save money with gas boilers is that the gas is 1/3 of the price for electricity.
The programs that has taken up the problems with nibes products failed to mention that allthough the price is much lower the amount of energy used is the same.
The spec for the houses suggests that a 360p would be sufficient but for some reason they seem to run on the immersion heater 24/7.
Some people that has been on the program had heating bills that would suggest an energy consumption of approximately 40MW annualy for a house less then 150m3.
A house that size with a consumption that high does not comply with the building regulations that it has been designed for.
Why Nibe did not comment on the reasons to why it did not work is a anyones guess.
But a very poor judgement from their part.

There is generally not a problem with heatpumps in Sweden as such, and the problems are not high energy bills.
Quite the opposite.
The problems are short life time (normally less then 10 years).
But a heat pump that is sufficiant in size for the house will pay it self in less than 10 years.

Carl, you nailed that on the head! I agree 100 percent with you!
