"Jim Farrell and North Alabama Technical Services rebuilt my computer and provided me with everything I expected and so much more.  He provided the various options in equipment, including specs and pricing, answered all our questions and helped us make the best decision for our purchases.  The computer was completed in a few days, far less than expected, the installation included clear directions for use.  The package also included a good warranty for the equipment.  I was extremely pleased with his service and would not hesitate to recommend his company to anyone with computer service needs."

"I required a new water heater installed and Diana builders were able to give me the exact water heater I wanted at the most competitive price. Dave took the time to explain what he thought the best solution was in plain English, gave me a quote a few hours later after researching his exact costs and stuck to his quote."

Install Boiler FAQs, answered by experts

Always consult your manual for specific pressure numbers. Many expansion tanks come pre-pressurized at a specific PSI range, anywhere from 12 to 40 PSI, designed for a range of home boilers. You should not have to pressurize an expansion tank yourself, only the boiler system. If your system has a tank that needs to be manually pressurized, this is generally a job for professionals and their tools.

It takes about five to 10 minutes for heat to reach a radiator, then about one hour until the radiator fully heats up a room. The exact duration depends on the size of the room and how far away the radiator is from the boiler heating system. Heating up an entire house could take up to two hours.

If you want a new boiler that’s going to help lower your fuel bills, you should buy one that has a high energy-efficiency rating. For example, a boiler that is rated “A” uses at least 90% of the energy created by the boiler. And in order to enjoy the best performance, it’s important to have it installed properly by a highly-rated tech.

Common problems include leaks, low pressure, and inefficient heating. Regular maintenance prevents many issues.

Most home boilers will need an expansion tank. That’s because these boilers are closed-loop systems, where the water is trapped. An expansion tank is needed when the boiler heats the water and it expands, allowing air to condense in the tank to make room for the water. Other types of boilers don’t use an expansion tank, such as traditional steam boilers, but these aren’t as common. And hot water tanks may be able to use a pressure release valve instead. When in doubt, call in a pro to take a look.
