Browse Forums Heating, Cooling & Insulation 1 Jun 15, 2012 4:25 pm We have just had a braemar ducted heater installed in our 12sq 2 bed house (TH320 3.7* 18kW 8 points in ceiling) and Ive noticed that the temperature fluctuates enough to really bug me. We set it to 21C and then end up in this cycle of feeling cold so bump it up to 23C and then back to 19C when it gets too hot. Why cant we just set it to 21C and have a reasonably stable amount of warmth? Is there something wrong with it? Did we make a mistake installing in the ceiling? I cannot contact the installer as they are impossible to deal with. I'd like to know what programming changes can be made to the unit. Please let me know if anyone has the braemar installation guide. TH series... Ducted heating temperature variations? 2Jun 15, 2012 5:45 pm I don't believe that there is any programming available on these systems. The most critical point is probably the placement of your thermostat, as this is what determines when the system turns on and off. If this isn't located correctly you will have problems. If it is located too close to an outlet then the system will turn off before the rest of the house has reached the set point. Outlet placement, duct size and return air location can also be a factor. I have a braemar in the ceiling with ceiling ducts (we are on a slab) and it works well. Our return air grill is mounted in the wall however. If it is in the ceiling the system will just pull the hot air back in, leaving the lower part of your room cold. Paul Re: Ducted heating temperature variations? 4Jun 18, 2012 9:16 pm Just check your thermostat as it may have something called energy efficient mode. You may even have to read the manual (real men dont need manuals). This mode will cause larger variations in temperature. If your thermostat is in the kitchen or close move it as cooking keeps that area warm and your heating wont fire up as often. Re: Ducted heating temperature variations? 5Jun 21, 2012 9:39 am I have the Spectrolink controller/thermostat on my system, but if I have it set to 21, it heats until it reaches 21 and then turns off. It turns back on before the room temperature display drops below 21, so I am guessing it turns back on before 20.5. I guess the actual temperature throughout the house will depend on other factors such as insulation, window coverings and vent locations.

We had exactly this issue in our old place - It was a 12sq 80s house, and when we added ducted heating 15 years on, the thermostat was placed in the stupidest place imaginable - in our tiny family room, close to the kitchen. Because it was quite a small space, it would heat up quickly and then the damn heating would switch off because it was warm in there, while the rest of the house was still freezing. The problem was compounded when the oven was on. This time round, we made sure the thermostat was in a (open) hallway and it works a treat. If this looks like the problem, perhaps it's possible to have the thermostat relocated? It seems very clear to me that your contract states that a security account does NOT need to be established so the answer to the builder is NO. If in doubt find a contract… 1 8512 The fastest thing a builder will do is bank your cheque, those systems work perfectly with lightning speed, everything else is slow burn. Just the way it is. 1 8711 Can someone please offer some advice? Im DESPERATE. Because I'm completely and utterly exhausted. How long are variations taking with other companies at the moment?
