Heat exchanger vs dual boiler

Sure, espresso is a great drink by itself, but it is the lattes and the cappuccinos that really conquered the world. There are many different parts to espresso machines that contribute to the amount and quality of steam they can produce. The two best espresso machine types for steam output are heat-exchangers and dual boilers. So you have one boiler for heating up water and another for steam, heat exchanger vs dual boiler.

Heat exchanger vs dual boiler

A double boiler has two boilers on a single machine. Each boiler for a specific function. One is the brew boiler, set at a lower temperature. The other is a steam boiler set at a much higher temperature. By keeping them separate, the user will have full control over the brew temperature and should be more consistent in the extraction. The heat exchanger has only one boiler set at steam temperature. When an extraction is done, the pump will push room-temperature fresh water from the water source and pass it through the heat exchanger. By thermodynamics and hydrodynamics, the water heats up as the water travels through the heat exchanger rod. The water should heat to a therearound sweet spot, perfect for espresso extraction while it exits. Double boilers were invented later than heat exchangers. The popularity grew when the coffee conglomerates in the USA were on a campaign to open many cafes worldwide. They want the coffee machine to be more predictable and to have a standard SOP to make consistent shots of expected quality, even from amateur baristas.

If you are a coffee roaster or a cafe and are stuck with an entire batch of coffee that you want to improve.

Double Boiler Espresso Machines covers the basics. Upside is much easier workflow and better consistency. If you can swing it cost-wise, DB is a no-brainer in my book having owned both. Machines like Lelit's MaraX, somewhat blur the line in terms of workflow and consistency, but it is a cost compromise, so I come back to to DB if you can. They said the main drawback to HX, according to the video, is the need to pre-flush.

As well as which boiler type is best for your needs. If you find the content in this video helpful, please like and comment so we know if we should make more videos like it. The machine warms up, stabilizing temperature in the boiler and the group head. When shot is pulled, water is pulled directly from the boiler. Temperature remains stable how stable depends on the machine. After shot is completed, the machine can be switched to steaming mode.

Heat exchanger vs dual boiler

There is a wide variety of espresso machines on the market, of which fully automatic machines take care of the entire brewing process at the push of a button. Boilers are essential components of any espresso machine. Thermoblock or single boiler machines are ideal for domestic brewing and are the most inexpensive. However, if you want to move your brewing up to another level by simultaneously pulling an espresso shot and steaming milk, heat exchange machines or dual boiler machines are your best options.

The quality of internal components and how they are engineered. Leave a comment Name. I don't get a blast of steam if I pre-flush as the machine in the video did. Contact us for availability.

Top 5 Compact Espresso Machines April 1, The two best espresso machine types for steam output are heat-exchangers and dual boilers. There are now a far larger number of designs variations than just HX or DB.

Fine Coffee Company is unable to provide any service, modifications, repairs or technical support for machines purchased not from its authorised local distribution source, grey imports or machines purchased from overseas. For double boilers, you will need to flush some water out of the grouphead. Sure enough, there is a delicate thermometer that takes the temperature of the water at this point and once it has reached the perfect temperature, then it goes to the grouphead.

A double boiler has two boilers on a single machine. Each boiler for a specific function.

Why have two boilers full of water? Content including all text and images in part or in whole may not be reproduced in any electronic or printed medium without prior permission. Or the lighter roast will benefit a little from the bitterness for a better balance. A VBM or Isomac from had to be flushed for ages to get to temperature. If you firmly believe that the water quality will heavily affect the extraction, then a heat exchanger should be your choice of machine. Please place orders early to prevent any inconvenience. As you do an extraction, cold water goes into the heat exchanger to warm up while the hot water exits. Increasing the temperature, or having a straight-line profile, might have some benefits. First, make sure that you can see the meniscus that bottom line at the top of your water in the sight glass. You control the output, and it is immediate steam on demand.
