Commonly Asked Questions

Q: Do you keep your baptistry heaters in stock?

A: Yes, we do keep a supply of most items in stock. Some baptistry heaters are built when orders are completed and sent to the factory. This helps keep the cost of labor and storage to a minimum. Most items are shipped out within 24 hours of purchase and take about 1-2 weeks for delivery depending where you are located in the country.

Q: What hours are you open? How can I talk to someone?

A. Our office is open from 9:00 AM - 5:00 PM, Monday - Friday (excluding holidays). We are located at 685 Tripple Creek Rd, Rocky Mount, VA. Our phone is 540-493-5928. If the line is busy we are helping other customers, leave a message and we will return your call promptly.

Q: I have purchased a heater kit from Calvary Supply but how can I install it?

A: Our Baptistry Heaters are easy to install. Any local plumber can install these units. We ask that you do not attempt to install the units unless you are a trained professional. This could void the warranty on the unit, including any accessories that you may purchase with it. There are instructions that come with each kit.

Q: What is your warranty, exchange and return policy?

A: Heaters can be exchanged within 15 days of purchase if found to be defective. After 15 days, items may be exchanged only if the unit is damaged or defective within the one year warranty period. See our returns policy for more information.
Q: How do you ship the units?

A: We ship via carrier (Fedex generally) straight from the warehouse to your church or mailing address. We ship each heater unit using UPS or FedEx standard ground freight. Typically, a unit can arrive within 1-2 weeks of purchase, as each unit is custom built in the plant and then shipped to your location. Once shipped, we can provide a tracking number if requested. We ship to all 50 States in the United States. Rush shipping (including overnight) is available at an additional cost. We do not ship overseas.

Q: What forms of payment do you accept?

A: We proudly accept MasterCard, Visa, and Discover Card. We also accept checks, and check by fax. Please make your check payable to Calvary Supply Company and please include the shipping, handling, crating, insurance fee. PayPal payment options are also available. If you wish, you can call us at 540-493-5928 and make your purchase via telephone.

Q: How quickly does a heater warm my baptistry?

A: Typically, a heater can heat you baptistry depending on how large your baptistry is and how powerful your unit is. The following chart can illustrate quickly any baptistry heater can heat your tank. If you have our 11.5kw unit, a 1,000 gallon tank will heat in approximately 8.6 hours (1000 divide by 115 Gallons Per Hour).

Reminder, all heaters are electrical products and should only be installed by a licensed electrician.
