FAQ's
What is the definition of CHP?
Combined Heat and Power (CHP) is the simultaneous generation of usable heat and power (usually electricity) in a single process.
What are the primary fuels for the Dachs?
Natural Gas or LPG
Why should I consider CHP?
There is no more efficient way of generating electricity and heat, and is therefore a recognised carbon saving technology. CHP is considered by the European Union and many other countries as an important technology for future CO2 savings.
But apart from the obvious environmental benefits, CHP users make savings on their energy bills - the more you run a CHP unit, the more you save.
What are typical applications for a Dachs micro CHP?
Sheltered Housing, Apartment Blocks, Leisure Centres, Luxury Houses, Fire Stations, Hospitals, Schools, Hotels and many more.
Can I use the Dachs in my house?
The Dachs is only suitable for domestic use in large luxury houses with either a swimming pool, underfloor heating or a large enough heat demand to keep the unit running for long periods of time.
I do not have a 3-phase electrical supply, can I install a dachs unit?
No, due to the type of generator in the Dachs a 3-phase electrical supply is required.
How often does the Dachs unit need to be serviced?
The Dachs needs to be serviced every 3,500 running hours. The control panel will alert you to the need for a service visit 300 running hours before the service is due.
Can I access information about my Dachs unit online?
Yes, the control panel on the Dachs unit comes complete with an integral modem which if connected to a dedicated analogue phone line allows both you and Baxi-SenerTec UK to login to a dedicated Dachs website.
What if I produce more electricity than I require?
It will simply be exported back to the grid.
What if the Dachs produces more heat than the building requires?
The Dachs unit will simply switch off until you have a sufficient heat demand to keep the unit running.
Does the Dachs unit have a back up function in the event of a grid failure?
No, for safety reasons the Dachs unit will automatically switch off if the grid stops working to avoid the possibility of any electricity being fed back onto a grid which is not running.
Can I connect easily to the national electricity grid?
Yes, the Dachs unit complies with the G83/1.1 regulations which means that you can connect the Dachs to the grid without seeking the permission of the local DNO. You do however have to advise the DNO once the unit has been commissioned that you have connected the Dachs to their grid. Each DNO has their own application form which needs to be completed. For more information on the G83/1.1 agreement please have a look at the technical section of this website.
Are there any grants available for CHP installations?
No, but you can apply for an interest free loan from the Carbon Trust or apply for an ECA grant. For more information on these please visit the useful links section within the contact us section of this website.
