Boiler Replacement -When to do it

Your boiler is on the blink. Now you have some big decisions to make. Do I get another opinion? How much will it cost to replace the boiler as opposed to fixing it? How much energy will be saved? Home heating with a hot water heating system is a very good way to heat. However, when the boiler does not work or leaks there are many things to think about. The troubleshooting ideas in this article will work for both steam and hot water boilers.



If there is no water running out of the boiler and it is just a control issue it may be best to get another opinion. If there is water running then there is a stop leak liquid that can be placed into the boiler as a temporary fix. It should be viewed as temporary and not a permanent fix. Either a section of the boiler will have to be replaced or the boiler may need to be completely replaced.

If the boiler is fairly new and the warranty will pay for some of the cost then replacing a section may be the way to go. Bear in mind though, that the warranty rarely covers the labor cost. Labor will need to be paid by the homeowner. If the boiler is more than 20 years old then it is a no-brainer, replace it, the increased efficiency combined with the age of the existing boiler make it a simple decision. Oil boilers especially are very much on a down hill slope by 20 years, gas boilers are often in better shape even though the efficiency is way down from what today's are. So bottom line, replace if older than 20 years. For boilers in the 10-15 year range it is often a very difficult call. Work with your heating service expert to figure the best option and I would definitely get a second or even a third opinion.

The next cause of trouble could be a failure of the controls on the boiler. Once again I would go with the 20 year rule. Unless the control that failed is relatively inexpensive I would replace the boiler. Often I have seen that when one control fails other controls are soon to follow and the beast becomes a money pit. This is especially true of oil burners. Many new boilers now come with a five year full replacement warranty that even cover labor. Once again the really hard questions come for those boilers in that five to fifteen year old age bracket. The questions get even harder when you are without heat, it is freezing outside and you do not have the time to get other opinions. At this point you have very limited options. Do make sure that you get a cost for the repair before you give the permission to fix the boiler. Electrical controls are not returnable once they have been installed. So once installed you bought them.

Questions about boiler failure and replacement are many. This should give a brief overview of the options that are available for the homeowner. There are many variables and often no answer is the completely right one. Many things depend on the situation of the homeowner, the age of the boiler, the cost of the repair, and the efficiency of the existing boiler as opposed to the efficiency of a new boiler. Many times that all adds up to a judgment call between the homeowner and the heating company.

Air condition system is no longer working and the person who checked it out says it needs a new system installed


get a second opinion when this statement is made
ac units only need replacing if parts are no longer available for repairs or the quoted repairs make it uneconomical to repair when compared to new units
for example
if your units is 15 years old, parts will be scarce and if it needs a compressor the cost of the part and labor will be close to the price of a new unit
new units are inverter units and are less costly to run and the larger units have reverse heating capability which makes them a heater unit in winter
best advice -- get a second opinion and then quotes for new units and make a decision on that information

From experience, a protection circuit has cut in, most likely due to a short in one of the DC output voltage rails on the PSU, thus giving the result of red standby LED, then green, then back to red. If the standby LED is not flashing/blinking, chances are you won't see any error codes.
This unit consists of several surface-mounted components, transistors, diodes, capacitors and resistors (many of which are miniature and often glued to the PCB) - this could become very costly, just in replacing modules as opposed to individual parts and spending hours fault-tracing looking for the problem which could cost a lot more in terms of labour.

I would recommend that you get a second opinion - take it to a service centre, obtain a quote for the estimated cost of repair (and fault diagnosis at the same time) - then you can make a decision after that.

It's up to you but before spending ANY money on it, throwing it out, or selling it somewhere as is, or whatever, get that second opinion from an authorized service workshop first. See how you go. *Nothing is impossible to fix, some things are complex.*

panasonic th42pz77u no pic or sound just 10 blinking light.


According to a reliable source, 10 blinks: Sub 5v SOS / Main 3v SOS DG Board DTV 9v SOS / Tuner Power SOS.

Your best bet is to submit the TV to an authorised Panasonic service centre, obtain a quote on likely parts/labour costs involved, along with a second opinion (as to the exact cause of the problems as confirmed), this will then allow you to make a firm decision afterwards on whether to go ahead or not.

Hello SusanWargin,
In my opinion ( and that is all it is).. I have always stood by the old litmus test whereby : if the cost to repair is close to or exceeds the cost to replace, then replacement makes sense. From the description you've presented and considering your micro is 12 years old, there is a reasonable chance that other components ( magnetron, transformer et al) will begin failing and end up costing more and more. So.. I would support your decision to replace with a new one. (again, this is only my opinion but I say this with sincerety and some experience with these appliances) ...Good Luck deciding..
