Combi Boilers Waste Energy


Combination boilers are called just that because they combine your hot water production and your space heating together with one boiler. The problem lies in the way that they produce hot water. To make the water hot, these boilers have a coil inside the chamber that the water for the space heating is held. The heat is transferred through the copper coil wall from the one water to the other.

The heat transfer of the efficiency of the transfer is not the problem. The problem is that you have to keep the boiler hot all of the time to make sure that you will have heat to make the water hot when you need it. To compound the problem you will find that boilers are typically very poorly insulated. The amount of heat that you will lose because of this poor insulation is unbelievable.

You have or are thinking about buying a Combi Boiler. Read this first because I will explain to you why you either have or are going to make a very big mistake.

Rather than go with this method of water heating, set up your boiler with a separate zone for an indirect water heater. Indirect hot water heaters transfer heat just as effectively, and they are usually very well insulated. The temperature drop in these indirect tanks is typically less than 1 degree F per hour. That’s not very much!

Keep in mind that even though this setup may cost you a bit more up front, that in the long run you will be saving more everyday. With the price of heating fuels going up daily you can bet that the indirect tank will pay for its self in a very short period of time.

Condensing Gas Boilers - The Best Radiant Heat Boiler


The right condensing gas boiler coupled with the right heat transfer system to get the heat into your home the right way will give you the most efficient heating system possible with today’s technologies. There are a few things that need to be taken into consideration for this combination to work well and serve you well.

For this type of heating system to work you first need to have a radiant heat system that will supply enough BTU’s to your home at very low water temperatures. By low I mean under 100F. To get the output that you need at this low a temperature you of ten will need to design the radiant heat system with heat transfer plates. The heat transfer plates will make the transfer of the heat from the tubing that the water flows in to the floor as efficient as possible. Getting the floor warm enough to heat your house with low water temperatures should be the goal.

Now that you have a great heat transfer system you can set up your boiler to run at very low temperatures also. Most of today’s condensing boilers use out door reset technology to assist in keeping the water temperature just high enough to help the heat transfer plates produce just enough heat to keep you warm. On the coldest day of the year you want your water temperature to be no more than 100F and still be keeping your house to the temperature that you want it to be.

A great high efficiency heating system coupled with a good high quality condensing gas boiler will give the best in comfort, quiet heating at the lowest cost possible. Sure this type of system will have a bit higher upfront cost. And the contractor that you hire to install this type of heating system may require a higher rate to perform the work, But once you experience the comfort and efficiency of a top notch heating system like this you will soon forget the money and enjoy your nice warm comfortable home.

My combination boiler vaillant turbo max is not building up presure what can I do ?


Check the warning pipe to see if water is coming out. If it is then the pressure relief valve is passing and will require cleaning\replacing. If the water in the system is dirty then the capillary tube to the pressure gauge may be blocked this normally means changing the gauge. If neither of those are satisfactory then you may have a leak on the heating system or heat exchanger.
If the pressure is going up but dropping off when the boiler cools down this indicates the expansion vessel diaphragm needs recharging or replacing

Pressure upto max nearly im my bolier


You don't say what kind of boiler this is but I'm going to guess that it is a hot water boiler.  If so, you have a combination valve which adjusts the water by pressure and bleeds off excess.  These valves do get corroded and dirty.  Shut down the boiler, shut off the feed water valve.  Replace the valve assembly.  Do not try to adjust these things.  Your new valve should maintain about 15 psi.

When it reaches between 1 and 1.5 bar, it is time to turn the white knob back to the right to close the valve. Be very careful not to over-tighten. 7) Turn the filling key to the left until the arrow lines up with the open padlock and remove the key.
