Q:Ok im getting slightly worried that I might have messed up my thermostat. Basically I stupidly screwed a bookshelf to the wall and it was very close to where the thermostat is. The heating now will come on for about 10 minutes or so and then goes off again. I think the boiler isn't that old as the places I am staying in is only about 5 years old. I see the burner light come on when I first start up the boiler then shortly after it goes off again. There is power going to the thermostat still but I am just wondering if this could cause the problem that I am getting. Any help would be much appreciated.
The Problem could be the boiler pump. If the pump has stopped working, then the boiler is only heating the water in the boiler, then shutting down. Put a long screwdriver to the pump body, and the other end to your ear. Then with the boiler on, listen to see if the you can hear the pump impeller turning. Good Luck.
Q:Hello, I just got a new eco boiler, and am trying to work out what would be the cheapest way to run it. There is 2 of us in the house and it takes 1 hour to heat the boiler for showers for both and plenty for washing up. The boiler doesn't have any outside insulation but it is 27+ degrees room temp here, so what do you think? 24 hours keeping the heat all day and switching it's self on and off. We really don't need hot water all day long. Or 1 hour a day running constant? Cheers :)
Your boiler will burn more energy running on demand from cold starts, than it will maintaining a consistent temperature throughout the day. Some types sold in the US have a vacation setting that will prevent it from cycling while away, but this option should really only be used if you will be gone for a long time. I'll assume the 27 dg room temperature is Celcius and not Fahrenheit, which doesn't matter too much however your boiler will operate more efficiently if it has an insulating jacket for cold days. If you insulate it the boiler won't have to cycle as often. Not sure about eco-boiler if it's the type that employs a tank or has a coiled heat exchanger, and if so may not require an insulating jacket. These types of boilers are already engineered to be efficient appliances so you'll do yourself a favor by letting it work on it's own and not turning it off while you're away.
Q:Hi - i don't know if anybody can help me... i am having a nightmare trying to repressurise my boiler. A Vokera Syntesi 25e. My filling valve is permanently connected so i did as my boiler instructions said to increase the boiler pressure and turned the filling loop to the vertically down position. I expected to hear water entering the boiler and the pressure to rise but nothing happened. My central heatign system is working fine - all radiators and warm water nice and hot - so I dont know what the problem can be. My pressure is below 1 bar at the moment so would like to increase it. The filling valve loop reaches from the filling valve (the one with the three normal/off/filling loop positions) along the loop to another tap on the left which has a black knob marked with open/shut in two directions. What is this and am i supposed to do anything with that? Any help would be much appreciated
sounds like a valving problem. you could have that 3-way valve in the wrong position. trace the pipe and make sure its piped to the fill line. besides that try the valve in all three positions and see if pressure rises. if not then maybe the valve is busted or there is another valve up or down stream that is closed. remeber not to fill too high because that water ur adding is going to heat up and make the pressure go even higher after alittle run time
Q:Three settings - Off , water , water / radiators. Off - no heating , no hot water Water - no hot water water / radiators - heating and warm / sometimes hot water. You can actually hear the boiler ' kicking in and out ' when you turn the taps / heating on. All i want is hot water on tap ( usual setting ) and heating when required. which bit is broke / needs looking at ? thanks
talk about confuse the issue, you say the boiler is firing when you turn a tap on ? if so its ok, heating settings do you have a wall stat? if so turn it up, whats your pressure reading ? should be 1-1.5 bars otherwise mail me using simple what works, what doesnt
Q:i am looking to buy a home built before 1890 and it MUST remain as is with it's natural gas boiler. how efficent is this system v's using forced air heating. keep in mind this home is 4800 sq ft and is all plaster walls and hardwood floors. i am sure i could help by using the 3 fireplaces but i am still concerned about the boiler having never seen one before.
How old is the boiler? Generally, the older the boiler, the less efficient they will be. But with an old house and 4800 sq ft. plan on spending BIG bucks on heating.
Q:I had been living in an illegal basement apartment in New York for about 2 years. At the same area behind a door were located the boilers/central heating system of the 3-level building. At the end of this 2 year period I noticed a painless lump on the left of my neck, I was diagnosed with Hodgkin's Lymphoma -which is blood cancer- a couple of weeks later. I immediately moved out just to be sure. Is there any knowledge that can prove, that I got sick because of energy/heat/radiation from the boilers, or something that I was breathing in there? Do you know if there is any legal action that I could take? I am too young to get this, and I have no family history.
A relapse with Hodgkins is amazingly prevalent. and unlike many different cancers, her odds are nevertheless really good for an total restore. in spite of the actual incontrovertible truth that Im effective your dcotor has gone over this with you, the traditional 2d line remedy with Hodgkins is a severe dose of chemo alongside with a stem cellular transplant. fulfillment prices are really good utilizing that approach. in spite of the actual incontrovertible truth that she could be in a position only to attempt yet another round of chemo without the stem cellular transplant. organic remedies do not paintings. in the adventure that they did human beings could be utilizing them truly then chemo. back earlier chemotherapy the survival cost on Hodkigns became about 5%, today its about ninety%. So please pass with regardless of approach her record advises. I favor you the finest of success, and that i know she will have the ability to get by this.
Q:We have relocated from FL and know nothing about the pros and cons of heating with radiators
Radiant heat is not as efficient as convection heat if that's what you are asking. If you purchased a house that already has radiant heat I would just go with it. The change out to a regular furnace would not really have a pay off and as stated you will get the comfort of a humidifier built right in. The best way to save on heating bills would be to head back to Florida. I have visited Tampa and I have to say I would not mind living in the Tampa/Clear water area.
Q:im living in a four bedrom house with my wife, daughter and son, currently with a conventional boiler and a 3 bar power shower.What are the options?
. It looks like the 'combi' costs more but delivers more. The big advantage with a combination boiler, or a combi as it is usually called, is that it not only delivers continuous hot water, but more importantly delivers it at mains pressure too. So, with a combi system you can have a really effective shower without needing an expensive Power Shower booster pump. Combis are also considered to be amongst the easiest systems to install,..... Then there's this ...If you looking to replace your existing gas or oil central heating boiler, you should consider buying a Condensing Boiler. Although these typically cost ?100-?300 more to buy and install than a conventional modern boiler, they should save this extra cost in as little as 4 years. A condensing boiler is a high efficiency modern boiler that incorporates an extra heat exchanger so that the hot exhaust gases lose much of their energy to pre-heat the water in the boiler system. When working at peak efficiency, the water vapour produced in the combustion process condenses back into liquid form releasing the latent heat of vaporisation. A side effect is that this water, known as condensate, which is usually acidic, has to be piped away to a drain or soakaway. ... ... The musewell site is informative. I think I'd go with the combi.
