"Aleman Plumbing contacted me right away for an appointment to look at my water heater. Their quote was advantageous compared the the other I received and they were able to schedule the work immediately. My water heater was in a difficult location and I also needed to replace a pressure control valve but Carlos got it all done very well and was great to work with."

"The plumber can over the same day and examined what needed to be done. Installation of a leak detector. A quote was generated and it was approved. The plumber arrived on time Sat morning and had everything ready to go. Well organized. Work was completed on time and we only had to have the water off for 2 hours. Not cheap but reasonable/competitive and they show up and get it done."

"Finally an honest Solar company!! I went through several companies trying to get quotes for one of my properties, either they were ridiculously expensive or they didn't return my calls. A friend of mine referred me to Mega Sun and I have to say I am very pleased. Within a couple days from the initial phone call I already had an estimate and once i decided to go with them the installation was completed in one week. Its been a little over a month since they completed the install and everything is working smoothly.

I was amazed at just how great the customer service was. I just want to say thank you to the whole team who helped out, I really appreciate all your hard work. Now I know you guys are the ones to call for all future jobs."

"I highly recommend Palm Construction for any home remodel job. We had them remodel our kitchen (including adding an island and moving the sink and dishwasher over to it), installing a new heater and air-conditioning, re-wire whole house, remodel bathroom and new flooring and paint throughout our 40+ year old home. Working with Ken and Jacob was super easy and they were very responsive to all of our questions and concerns along the way. The crews that showed up each day always came on time and did a fabulous job and cleaned everything up each evening. Despite living in the house during this massive remodel (with a toddler!) overall it was pretty painless. We had gotten seven estimates and while their price fell in the middle, we feel that they were well worth it and more! Our house feels like a brand new home and is so more livable!"

Water Heaters FAQs, answered by experts

There are pros and cons to tankless water heaters. They are more efficient than traditional tank water heaters, and maintenance costs are lower. These units are also much more compact. On the other hand, they cost about twice as much to install as traditional tank water heaters and are more limited in terms of flow rate.

No. Expansion tanks must be installed on the supply side (where heated water flows out) of the boiler. There’s also a list of other requirements for most boilers, including being above the pressure relief valves, being on the inner side of any circulator, and more. Your installation manual should have more information on expansion tank installation requirements and what sort of tank the system is made for.

The average cost to install a new water heater is approximately $1,300, with a typical price range between $880 and $1,800. The final cost depends on several factors, including the type and size of the unit, its location and accessibility, and the amount of labor required. For example, installing a unit in a tight space like a crawl space can increase labor costs. The type of water heater significantly impacts the price: while a conventional gas heater might cost less than $1,000, tankless models can cost around $2,600 to install (and up to $3,500), and solar heaters can cost upwards of $3,700. Other factors that can affect the total price include the fuel type, vent system requirements, permits, and whether any additional plumbing work or repairs from previous water heater damage are needed.

You have more options for water heaters than ever before. The best one for your home depends on your hot water usage and budget. Some of the more common types of water heaters are the conventional gas heater, a heat pump water heater, or a tankless heater for smaller homes or those with less water demands. Some uncommon types are solar and point-of-use systems. Some homes may have a combination of two units, such as a large heat pump heater and a backup point-of-use system.

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.
