DIY plumbing is all nice and great when dealing with small simple jobs, however what will you do when you have to tackle some more serious jobs?
The bigger the boiler job, the bigger the boiler installation price that you will have to pay in order to get it done by a local professional plumber, even though if you are a active diy enthusiast you could actually handle it yourself. Before proceeding, it is imperative that you understand that installing a boiler is not a job that can be taken lightly. In fact, there are a lot of risks and problems that can occur in the long run. If you do not feel comfortable, safe or satisfied with the job that you are doing, do not hesitate to call a qualified gas certified engineer to do the installation for you.
Choose the boiler
The first thing that you will have to do is choose the actual boiler. There are 2 major choices that you have at your disposal. You can either choose gas or electric boilers, depending on what suits you better, the area that you live in as well as the needs that your household has. One thing to remember here is that the electrical boiler is a far safer choice than the gas one, however it is slower to warm up and it might take a bit of time before building up a reliable supply of hot water. The gas alternative, although it might be a bit riskier, it is actually a lot faster and able to provide better overall boiler replacement cost performance.
One last thing to mention here is the fact that the electrical boiler is better suited for small households and apartments. It actually consumes a lot of power and can rack up quite the bill if used constantly by a larger household. The gas boiler is better suited for larger households with 4 or more members. This is because overall it is a far more financially advantageous option and is able to heat up water faster and a lot more reliable than the electric one.
Installing the boiler
You will need a standard plumbing tool set, along with a lot of sealing tape and hemp fibers. All boilers come with the extra tools that they need and the instructions in the actual box, so you will not be going in blind. The first thing that you will have to do is mount the boiler into position and connect it to the designated pipes. Remember to cut off the water supply in the entire household before doing so. This will prevent any unexpected leaks and problems. Take your time while doing this, use a lot of hemp fiber and sealing tape in order to create tight seals. Remember to check the seals constantly and make the necessary adjustments. After those pipes are connected, it is time to connect the power / fuel to the boiler.
If you chose an electrical boiler, then things are easy. Make the necessary connections to the fuse box and power grid and then connect it to the boiler. Make sure to collect any excess water and moisture before connecting the boiler though.
If you chose a gas boiler, things get tricky.
First off, shut off the gas pipe to your house and start making the necessary adjustments to the system. Make sure to bleed the system out first, there must not be a single bit of gas in the pipes when you get started.
Take your time, seal all the connections properly with both sealing tape and hemp fibers. After all the connections are made, turn the gas back on and check the seals. Use soapy water and rag. Simply put soapy water on the seals and wait to see it if bubbles. If it does, shut off the gas immediately and redo the seal. Vent out the house to make sure that there will be no gas left and try again.
While this job is a bit trickier and a bit more risky, at the end of the day it is still doable by a DIY plumbing enthusiast. Do remember to play it safe and if at any times you feel even the slightest concern or hesitation, then contact your local plumber and have him come take a look at it.
