Frequently Asked Questions

Why is #21EHPCONG going hybrid?

We are going hybrid because some people may not be able to travel as a result of the pandemic or its associated impact. Making the Congress more accessible helps Euroheat & Power and our members to achieve its underlying mission to elaborate and advance district heating and cooling, and to expand its scope of application and contribution to all the communities by reaching a much larger audience.

Given the current COVID situation, why not go to fully virtual?

At this point, we are very confident that the in-person event will take place. It is impossible to fully replicate the richness, chance encounters and energizing atmosphere of an in-person event. However, if circumstances dictate, we will be ready to transition to a virtual format.  The good news is that this has little impact on the work currently underway to develop the congress programme.

Why is it not all virtual?

No virtual event, however well-orchestrated and executed, can fully replace an in-person event. Many people feel that they get more value out of hallway interactions and participants also cherish the opportunity to reacquaint with friends and colleagues in a face-to-face event. Unless COVID restrictions mandate that we pivot to a completely virtual congress, which we doubt, we are vigorously planning the greatest-ever hybrid event for both the people in Vilnius and online.

Will the virtual content differ from the onsite content?

Just in the way the session will be delivered, content is king and will be provided in the most engaging way whether you are onsite or online.

As a online attendee, would I be able to ask questions or participate in discussions?

Yes, we aim for an immersive experience and will facilitate interaction and continue the dialogue and information sharing.

Once registered as an onsite participant, can I change my registration to the online only? Or vice versa?

Yes, changes either way will be possible.  We strongly recommend registering to the onsite event, which will give you access automatically to the virtual event as well.

Invitation letter for visa applications

Non-EU citizens may need a letter of invitation from the congress organisers in order to obtain a visa for entry into Lithuania. This procedure is intended to assist participants who need to obtain a visa or permission to attend the 40th EHP Congress and is not an official invitation covering fees and/or any other expenses or financial support from the congress.

We advise you to start the visa application process as early as possible and no later than six weeks prior to your departure. The organisers are not to be held responsible for the outcome of your visa application.

All participants must register and pay the required registration fees before requesting an official letter of invitation. The registration fees are refundable should the visa application be denied.
