Do both my boiler and water heater need their own expansion tank?

• <div><p>Unless they are connected to the same system, boilers and water heaters will both need their own expansion tanks. The only case they wouldn’t have separate expansion tanks is if the boiler is pulling double duty and managing a heating system while also supplying hot water for a home. In which case, you may not need a hot water heater. </p></div>

Q: Can you switch from a tank to a tankless water heater?

• <div><p>Going from a tank to a tankless water heater is one of the most effective ways to lower your utility bills. The switch also frees up more space and ensures a consistent hot water supply, as the water is heated on an as-needed basis. It costs between <b>$5,400 and $7,400</b> to install a new tankless water heater. Most installation companies will also help dispose of your old water tank.</p></div>

Q: Are water heater pans required by code?

• <div><p>Yes, most municipalities have codes that require water heaters to have pans. A pan is necessary when a water heater or hot water storage tank is installed in an area where water leakage could cause damage, such as an attic, second floor, or finished basement. Tankless water heaters are not required to have a pan since there is no storage tank.</p></div>

Q: What are some common issues with a water heater?

• <div><p>Often, the first issue you might encounter is a lack or loss of power&mdash;this could be caused by a tripped switch or a failed heating element. If your hot water is not producing enough power and its size is not the issue, you might need to replace one of its heating elements. A leaking water heater could be caused by tank erosion. </p></div>

Q: What’s wrong with high water pressure?

• <div><p>Excessive pressure (above 80 psi) puts too much stress on plumbing pipes, joints, and fixtures. This can lead to leaks and burst pipes. Plus, it shortens the lifespan of appliances, can waste water, and can raise your utility bills. High water pressure might feel like a gift, but it&rsquo;s actually a silent threat to plumbing. </p></div>

"Hired Neli for a virtual repair of our Whirlpool washer. Tom was VERY knowledgeable, friendly and professional. We came up with a solid diagnosis of my issue and the replacement parts required. Tom advised me to consider the value of repairing, parts costs and time required, vs. a new purchase and the effort to repair was not going to be simple. We chatted about the pros/cons a lot. As the washer was 6+ years old and there were holiday sales I opted to purchase a new unit. This is the 3rd time I have worked with Neli. All instances have been very productive and positive. "
