This web site is dedicated to contractors and professional installers. If you are a home owner looking to purchase any of the products listed on this web site, please either have your installer contact us or purchase directly from our retail web site at GlobalTowne.com.

ProWaterHeaterSupply.com is the only Exclusive Bosch Wholesale Online Retailer. Our expert sales staff is trained on the complete line up of Bosch Tankless Water Heaters. We know them inside and out. We can also help you compare Bosch heaters to those of the other major manufacturers.

It is our goal to turn every sale into a Bosch Tankless sale. Looking for a conventional tank water heater? You will need to look elsewhere, because we do not sell them!

We buy directly from Bosch in quantity and we are therefore able to pass along savings directly to our customers. We will match or beat any published online sales price from other Bosch Authorized distributors. [Sorry, but we cannot match the online pricing of unauthorized dealers. We regret to inform you that there are a number of private online sellers who are selling stolen heaters. Beware of these dealers because Bosch knows the serial numbers of these stolen heaters and they will not warrant them.

We have multiple warehouses across the United States. Our warehouses are full of Bosch tankless water heaters and we also stock a huge quantity of the 3" and 4" Z-Flex Z-Vent Stainless Steel venting (AL29-4C) required by the following Bosch tankless water heaters:

• Bosch Therm 940ES
• Bosch Therm 830ES
• Bosch Evolution 500
• Bosch Therm 660EF
• Bosch Pro 715ES
• Bosch Pro 635ES
• Bosch AquaStar 2700ES
• Bosch AquaStar 2400ES
• Bosch AquaStar 2400E
• Bosch AquaStar 250SX

As such, we are able to ship most of our customers' orders either the same day or the next business day. Most delays in shipping are due to our Fraud Prevention efforts that ensure that our Customers' credit cards are not being misused.

We care very much about our customers' privacy. Please see our Privacy Policy. We also work very hard with each customer to minimize returns. Please see our Returns Policy for more details.

Pro Water Heater Supply has the Lowest Return Rate of all Bosch's Authorized Distributors. Why? Because we look at each and every order before we ship to ensure that the heater makes sense.

Regarding Pricing: Our Bosch list prices are the lowest prices at which Bosch will allow its Authorized Distributors to sell. So, our Sale Prices are true Sale Prices. We do not inflate the cost of the heaters just to mark them back down.

Many of our heaters are shipped with FREE GROUND SHIPPING via Ground service to destinations in the continental US. And with four warehouses across the US, we are able to deliver most of our products within two business days via Ground Shipping.

Many of our smaller parts ship with a small shipping charge. However, even with these small shipping charges our prices beat our competitors who raise their prices and offer free shipping. Just compare!

A note about our stock levels: We maintain a large stock of all the products we sell. Some of our competitors show their stock levels on their web site and we are amazed at how low their quantities are!

Our stock levels are *much* higher than those of our competitors. As such, we are almost always able to ship your order COMPLETE with no delays.

We have very close relationships with our vendors, so if you experience a problem we can bring in the right people from the manufacturer to help quickly resolve your issue.

At Pro Water Heater Supply we care about our customers. We will spend the time with you on the phone before your purchase to help you pick the best products for your customer’s needs. Give us a try!
